I wasn鈥檛 expecting to see the moose, which is a ridiculous thing to say considering I was running through an area known for attracting them: Kawuneeche Valley, on the western side of Rocky Mountain National Park. I had just started my run and was only about听200 yards from the car, so I wasn鈥檛 in a wildlife-encounter headspace. But there it was, standing on the opposite听side of the Colorado River, as tall as me听and听a thousand听pounds heavier, with a massive rack.
That鈥檚 the thing about the park:听awe-inspiring sights听come easy here. Elk gather in herds on the east side, while听moose patrol the other. In between are bighorn sheep, mountain lions, and black bears. And that鈥檚 just the wildlife. The 265,807-acre park, located in northern Colorado, offers some of the best听access to high-alpine terrain in the country, thanks to 鈥攖he highest paved highway in America鈥攚hich tops out at a 12,183-foot peak, one of more than a听hundred听in the park听taller听than 11,000 feet.
The lower elevations,听below 9,000 feet and referred to as听the montane,听are dominated by broad, grassy meadows filled with more than 350听miles of trails. The subalpine environment, from 9,000 and听11,000 feet, is comprised of natural lakes, boulders, and evergreen forests, and听the majority of trails meander through these breathtaking听landscapes. And at 11,000 feet, the alpine ecosystem听begins:听trees give way to windswept tundra, craggy peaks, and cirque glaciers,听and the crowds dissipate, leaving you with the 鈥渞oof鈥 of the park mostly to yourself.
I spent three years living in Denver, exploring the park as often as possible, sliding down its glaciers听and wooing my soon-to-be wife in primitive campsites deep in the backcountry. Later, after moving away from Colorado, my wife and I would geek out on showing the park to our kids during听long family road trips. They would earn their first Junior Ranger badges听here. Eventually, we鈥檇 hold a memorial service for my wife鈥檚 grandfather on the edge of his favorite backcountry lake. There鈥檚 something personal to be found by anyone听in this landscape, a standout even in a park system that only protects the most awesome swaths of land in the country.
What You Need to Know Before Visiting听

Altitude sickness is real. It can be as mild as a light headache or as severe as vomiting and disorientation. If you鈥檙e coming from sea level, try to take it easy when you first arrive, and听schedule听tougher hikes later in your visit. Drink lots of water throughout the day, and eat regularly.
Pay attention to road closures. The park can get snowstorms into June, and some years snow will linger into July, affecting which roads are open. The park offers real-time road updates on its听, so check the information regularly.
Expect unpredictable weather.听The temperature can vary by 20听to听30 degrees between high elevations and the lower valleys, and summer thunderstorms come on fast. If you鈥檙e hiking above the tree line, keep your eye on the horizon for sketchy clouds forming,听and always have an escape route in mind. Midsummer snowstorms aren鈥檛 unheard of either. All of this to say: be prepared for any sort of weather in this听park, regardless of how warm it is when the day begins. Bring extra layers, and always carry听a rain shell in your pack.
Plan for crowds. Rocky Mountain National Park is the third most visited park in the country, and it鈥檚 only getting more popular鈥攙isitation听hit record numbers in 2019, pulling in nearly 4.7听million听people. Parking lots in scenic听areas like Bear Lake fill up before breakfast, and Trail Ridge Road听is packed with minivans and RVs by 10 A.M. If you have your heart set on seeing some of the park鈥檚 signature features, accept that crowds are part of the experience.听If you want to minimize interaction with those crowds, get started as early as you can鈥攅ssentially before dawn鈥攁nd head to Grand Lake, on the western side; roughly 80 percent听of all visitors enter through Estes Park, on the eastern side. If parking lots are full, don鈥檛 fret; the park has a good shuttle system that will take you to popular trailheads. Use it.
How to Get There听

Rocky Mountain National Park acts听as a sort of gateway to the mountains beyond Denver听and Boulder. Most folks fly into Denver, 80 miles southeast, and either rent a car or hop听the 听that brings visitors from the airport to the town of Estes Park and the main entrance, Beaver Meadows.听The other three entrances, Fall River and Wild Basic on the eastern side听and Grand Lake on the western side,听receive听far fewer visitors. The park runs a from the to popular trailheads like Glacier Basin and Bear Lake, but there鈥檚 no public transportation into the western side of the park.
The Best Time of Year to Visit

Most people frequent听the park in the summer, which has as much to do with the weather as the public-school schedule. Given its location and high elevation, the park has a limited summer season, and most roads are snow-packed during the winter months.
Winter
If you really want to escape the crowds听and don鈥檛 mind temperatures in the teens, is your jam. Trail Ridge Road, the only road that crosses the park, is typically closed from the end of October to May due to snow, while avalanches are a concern and snow depth affects trail access. But many of the park鈥檚 byways, like 听and even portions of Trail Ridge Road, become cross-country听skiing and snowshoeing playgrounds during the winter. There鈥檚 even an abandoned ski resort, Hidden Valley, located on the east side of the park, that attracts sledders and听backcountry skiers. Grand Lake, the听town on the western side of the park, has a bona fide 听with 22 miles听of groomed trails.
Spring听
Snow lingers well into May in these alpine environs, so spring tends to be a听warmer continuation of winter, with temperatures hovering between 30 and 50 degrees. But wildlife starts to get more active in this period, particularly the bighorn sheep, which are lambing in the spring. If you want to avoid the snow, stick to the Estes Park side, which gets significantly less in April and May than the Grand Lake side. Some years, lower elevations see temperatures hitting the sixties听in late April.
Summer听
Trail Ridge Road is typically open by Memorial Day, and things really get hopping in June. You鈥檒l still find drifts of snow at higher elevations (we drove through in July one year, and the snowbanks on the sides of Trail Ridge Road were higher than my van), but you鈥檒l also find wildflowers popping up throughout the high-elevation tundra and lower-elevation听meadows from June to August (head to the East Inlet Trail or Cub Lake for guaranteed sightings). Temperatures can reach the mid-eighties, but you could also encounter听a freak snowstorm at the highest elevations. Afternoon thunderstorms are common.
Fall听
You could argue that the months of September and October are the best time to visit the park, especially if you can swing a midweek trip when the majority of potential visitors听are working or in school. While fall might bring the occasional snowstorm, the roads and trails remain open into October most years. Temperatures are mild during the day, reaching the high fifties, and the aspens听begin changing in the middle of September. That magical show is only matched by the elk rut鈥攚hen听large males start fighting and bugling for the affection of females鈥攚hich commences in September and carries on into October听and can be witnessed at the Horseshoe Park area at dawn and dusk.
Where to Stay in and Around Rocky Mountain National Park听

This is one of the few national parks without an overnight lodge, but there are five front-country campgrounds (from $30). , , and听听fill up well in advance (make reservations up to six months prior to your date), while the听听and Campgrounds are first-come, first-served. Moraine Park, near the eastern edge of park, is the only campground open during the winter, and it鈥檚 available on a first-come,听first-served basis听during that season.
The best front-country camping is at Aspenglen, located听near the eastern Fall River entrance, a short jaunt off Trail Ridge Road. The 52 sites are surrounded by Douglas firs and听lodgepole听and ponderosa pines. Snag one of the five secluded walk-in tent sites on the loop. For a more primitive experience, show up early for one of the 26 tent-only sites at Longs Peak, which sits on the听southeastern border of park at an elevation of 9,500 feet and puts you within day-hike distance of Chasm Lake and the park鈥檚 signature Longs听Peak, reached by a 15-mile round-trip trek via the Keyhole Route (discussed听below). Plan on bringing all your food with you as听the Trail Ridge Store, next to the , is the only restaurant inside the park.
The park has 120 designated backpacking sites scattered from the relatively low elevations of Big Meadows, near Grand Lake,听to the Boulder Field campsites that sit above 12,000 feet en route to the Longs Peak summit. Get a wilderness permit ($30) at the 听next to the听听(near the Estes Park entry point) or at the听听(near the Grand Lake entrance).
Beyond the Park听
If you need a bed and electricity (no shame in that), you鈥檒l need to look outside the park. You can find any level of accommodations in both Grand Lake and Estes Park. On the Grand Lake side of the park, has a handful of log lodgings听on the North Fork of the Colorado River (from $160). In Estes Park, there are of standalone cabins and cottages for rent, including Solitude Cabins, a collection of 30 properties scattered听across nine acres that are abiding by 听(from $275).
What to Do While You鈥檙e There听

Hiking听
Yes, is going to be crowded, but you can鈥檛 beat the bang for your buck on this 3.5-mile round-trip, which听skirts the edge of some of the park鈥檚 prettiest alpine lakes and has views of dramatic peaks, including Longs and Hallett. The prize is听reaching Emerald Lake, which is framed by the 12,000-foot mountains of the Continental Divide. Keep an eye out for elk at the edges听of the lakes and pikas and marmots in the rock outcroppings along the trail.
Colorado has 14 named glaciers, six of which lie within the park鈥檚 borders. might be the most spectacular and most fun to explore. It鈥檚 a popular practice ground for beginner mountaineers looking to test their ice-ax听and crampon skills, and the mellow slope (less than听30 degrees) means you don鈥檛 have to worry about avalanche danger. Reaching the glacier requires a tough听ten-mile round-trip hike that begins at the Glacier Gorge Trailhead on east side of park, then passes听 and听听on its way to Andrews Tarn, a small lake that gathers glacier water at the bottom of Andrews Glacier.听Most days听all you need are a good pair of winter hiking boots and some trekking poles to get to the bottom of the glacier.听If you decide to explore the glacier properly and climb to the top with technical equipment, keep an eye out for crevasses, which have been known to form here.
Sample the park鈥檚 high-elevation听tundra along the 4.8-mile point-to-point Ute Trail, which begins just west of the Alpine Visitor Center at the high point along Trail Ridge Road. The entire route听is above tree line and tops out听at 11,660 feet along Tombstone Ridge, affording听views of Forest Canyon, the Continental Divide, and Longs Peak. In the summer, this trail听a perfect place to admire wildflowers, with species like the snowlover, alpine sunflower, and white alpine phlox popping up after the snow has melted.
Peak Bagging听
At 14,259 feet, Longs Peak is Rocky Mountain National Park鈥檚 highest mountain and its听only fourteener. Depending on your experience level, it鈥檚 possible to听knock this summit out in a long day, or camp at the base of Longs and turn it into a two-day adventure. While this is often the first fourteener for more advanced climbers, the route is a series of sheer vertical cliffs, narrow ledges, and year-round winter conditions,听and the听amount of exposure on the final mile of the ascent is severe enough to turn many would-be summiters away. The 15-mile round-trip , which starts at the Longs Peak Trailhead in the east side of the park, is the most common approach. Follow the East Longs Peak Trail for six miles to the aforementioned Boulder Field campsite ($30 a night; make a reservation six months in advance), where dry-stack rock walls help protect the nine established tent sites from the wicked winds at 12,740 feet. The sites sit just before the home stretch of the summit,听giving听you the chance to turn this expedition into an overnight adventure.听From this point on, things get real as you ditch the established trail and follow a series of cairns and painted bull鈥檚-eyes through the Keyhole itself, a rocky notch between Longs and Storm Peaks, and onto the steep听southern slope of Longs. The crux is crossing the Narrows, an exposed ledge with fatal consequences if things go awry. Be sure to attempt this when there鈥檚 no ice on the route and at less crowded times.
Rock Climbing
Hiking might be the number-one pastime in Rocky Mountain National Park, but you could argue that this is really a climber鈥檚 park, thanks to massive cliffs that dominate its听high-altitude peaks. There are nearly 500 established climbs, most of which are alpine affairs that require big days with long approaches. The bulk听of the climbing is traditional, and much of it requires several pitches and descents that are way sketchier than the ascents. There are plenty of routes in the 5.9 to 5.10 range, though there are big lines for beginners, too, including , an alpine route that combines Class 4听scrambling with 5.4-rated traditional climbing on 13,514-foot Ypsilon Mountain in the northern section of the park. Longs Peak has the most established routes, ranging from 5.4 to 5.12. You can even find destination-worthy bouldering in the park鈥檚 central , which sits听near Emerald Lake at 10,000 feet and has at least 100 problems, with something for everyone. But for a solid intro to what rock climbing is like in the park, head to the Glacier Gorge area, seven miles south of the Beaver Meadows entrance on Bear Lake Road, and climb the north ridge of the Spearhead, a seven-pitch adventure with a six-mile approach that requires some route finding. Once you鈥檙e roped up, expect a 5.6 climb with a little of everything鈥攋ugs, cracks, corners, and a short scramble to the peak, where a grand view of the gorge lies below.
Wildlife Viewing听
While many of the large animals, like grizzly bears and gray wolves, were extirpated from the park in the early 20th century, there are plenty of charismatic megafauna living within its borders. The park estimates its elk population to be between 600 and 800, while the bighorn sheep have reached a population of 350. Moose were reintroduced to the park in the 1970s and are thriving, especially in the meadows on the west side of the听Continental Divide. If you鈥檙e lucky, you鈥檒l see plenty of wildlife from your car, but it鈥檚 a hell of a lot more fun to spy animals (from a safe distance) while on foot. The 10.6-mile out-and-back East Inlet Trail to Lone Pine Lake, on the west side of the park, offers a good opportunity to see moose, and the hike passes Adams Falls and ends at Spirit Lake, so it鈥檚 a win even if there are no moose in sight. Bighorn sheep are active throughout the day and can often be seen posing on cliffs at higher elevations. They also like the salt deposits in the meadow around . You鈥檒l see so many elk that you鈥檒l stop counting, especially on the east side, which is home to massive herds鈥攜ou鈥檒l even see them in the town of Estes Park. If you鈥檙e hiking in the subalpine areas of the park鈥檚 central Bear Lake, keep an eye out for pikas and marmots, which scuttle around outcroppings throughout the forest. Black bears make a point of avoiding humans, so they鈥檙e not often seen.
Road Cycling听
Trail Ridge Road cuts through the heart of the park,听connecting Estes Park with Grand Lake via 48 miles of pavement. Yes, it鈥檚 the main thoroughfare into the park for vehicles, but it鈥檚 also a road cyclist鈥檚 dream, climbing 4,000 feet from Estes Park to the summit, with a solid 11 miles听cutting above the tree line. An out-and-back on Trail Ridge might be one of the most spectacular centuries you can do in the U.S. If you鈥檙e not interested in climbing, there are shuttle companies that will drive you to the top of Trail Ridge Road so you can cruise down. If you鈥檙e looking for gravel, check out , near Estes Park, which was the original road up and over the Continental Divide. It鈥檚 a little over nine miles from point to point, climbing 3,180 feet, with an average 7 percent grade and stretches of hill that max out at 20 percent. You can do a killer sub-50-mile loop that has you climbing Old Fall River Road and bombing the pavement of Trail Ridge听back into Estes Park. Bonus: both of these roads are typically open to pedestrians and cyclists a month before rangers permit access to cars. If it was a mild winter, you can enjoy听the entire month of April on Trail Ridge听without any traffic.
The Best Places to Eat and Drink Around the Park听

Estes Park is definitely the unofficial gateway to Rocky Mountain National Park, so it can feel a little bit touristy, but you can鈥檛 argue with the location: surrounded on three sides by the park听and a little more hipster sophisticated than Grand Lake, which leans more toward听old-school rustic. Order online a听wild-game meatloaf and a smoked old-fashioned to-go from听. , in the heart of downtown, has organic fair-trade drip coffee for about $2听as well as a mean vegetarian burrito. Drive 45 minutes from the eastern edge of the park and you can make a pilgrimage to in the town of Lyons to pick up a six-pack.听If you鈥檙e coming through Grand Lake, is currently doing takeout orders.听Down the street, 听offers听a good selection of Colorado beer.
If You Have Time for a Detour听

Bring your mountain bike and head west from the park into Grand County, where 听operates Trestle, one of the best lift-served听mountain-bike parks in the country, now featuring听a new gondola to whisk you to the top of the mountain. Twenty miles north, 听has a lift that serves gnarly downhill and flowy cross-country trails alike. Spend an afternoon recovering in the pools at the , or search for the primitive Radium Hot Springs, which are carved out of the Colorado River south of the town of Kremmling.
North of the park, raft the Class III鈥揑V , the only designated听National Wild and Scenic River in the state, which passes through . It鈥檚 an ideal way to spot听bighorn sheep on the Poudre Canyon cliffs. On the east side of the park, drive through听the 25-mile-long Big Thompson Canyon from Estes Park to Loveland. The granite walls host rock climbers while sporadic roadside pullouts offer premier fly-fishing.
How to Be a Conscious Visitor

The park鈥檚 original conservation group, the Estes Park Protective and Improvement Association, made this declaration back in the day: 鈥淭hose who pull flowers up by their roots will be condemned by all worthy people.鈥 We couldn鈥檛 agree more, but being a good steward goes beyond not picking the flowers. Whenever hiking above the tree line, stay on the trail. Exploring听the park鈥檚 high-alpine tundra is a treat, but keep in mind that plants and ground cover growing at such听elevations are especially sensitive. Use the bear boxes at the campsites to store your food, and don鈥檛 bring firewood into the park (mountain beetles have devastated the pine forest surrounding Grand Lake).听If you鈥檙e visiting the park in the winter and exploring the backcountry, follow avalanche-safety protocols and wear an avy听beacon at all times. Better yet, go with a guide if you鈥檙e unsure of how to handle that sort of terrain; 听has full-day tours starting at $210.
