Rocky Mountain National Park is Colorado’s crown jewel — 415 square miles of alpine tundra, glacier-carved valleys, and some of the most accessible high-altitude wilderness in North America. With 14,259-foot Longs Peak anchoring the skyline and Trail Ridge Road crossing the Continental Divide at over 12,000 feet, RMNP delivers a mountain experience that genuinely lives up to the hype.
The park sits 71 miles northwest of Denver and welcomes over 4 million visitors a year, making it one of the most visited national parks in the United States. Despite the crowds, it’s remarkably easy to find solitude — most visitors stick to a handful of popular trailheads, leaving hundreds of miles of backcountry largely empty.
Park highlights: Trail Ridge Road, Bear Lake, Longs Peak, elk rut in September, wildflower season in July, moose in Kawuneeche Valley, and 350+ miles of hiking trails.

The America the Beautiful Pass is the obvious choice if you’re visiting more than one national park or federal recreation area in a year — it covers entrance fees at over 2,000 sites nationwide including all Colorado national parks and most state recreation areas.
Timed Entry Permits: From late May through mid-October the park requires a timed entry permit in addition to your entrance pass. Permits open 90 days in advance on recreation.gov and sell out fast for peak summer dates. Check the NPS website for current year permit requirements as dates and procedures change annually.
Top Hikes in Rocky Mountain National Park
Bear Lake Loop (0.8 miles, easy)
The most accessible trail in the park — a flat loop around a stunning glacier-carved lake at 9,475 feet. Crowded by 9am in summer. Go early or take the park shuttle from Estes Park. Great for families and first-time visitors.
Emerald Lake Trail (3.6 miles round trip, easy-moderate)
Starts at Bear Lake and passes Nymph Lake and Dream Lake before reaching Emerald Lake at 10,110 feet. One of the most rewarding short hikes in the park — three distinct lakes, increasingly dramatic scenery, manageable elevation gain of 605 feet.
Sky Pond Trail (9.4 miles round trip, strenuous)
One of the park’s best full-day hikes. Passes Alberta Falls, Loch Vale, and a scramble up a waterfall to reach Sky Pond at 10,900 feet. The scramble section requires using your hands — not technical but not for the timid. Worth every step.
Chasm Lake Trail (8.4 miles round trip, strenuous)
Leads to a dramatic cirque lake directly below the east face of Longs Peak. Even if you’re not climbing Longs, this trail delivers one of the most impressive mountain views in Colorado. Elevation gain: 2,360 feet.
Longs Peak (14.5 miles round trip, extreme)
Colorado’s northernmost 14er and one of the most climbed high peaks in the state. The standard Keyhole Route is non-technical but requires scrambling on exposed ledges above 13,000 feet. Start no later than 3am to summit and descend before afternoon thunderstorms. Not recommended for beginners or anyone without high-altitude experience.
Flattop Mountain (8.8 miles round trip, strenuous)
A less-crowded alternative to the Bear Lake area trails. Summit at 12,324 feet with views across the Continental Divide. Connects to backcountry routes into the park’s remote west side.
Trail Ridge Road
Trail Ridge Road is the highest continuous paved highway in the United States, crossing the Continental Divide at 12,183 feet and offering unobstructed views of tundra, glaciers, and mountain ranges stretching to the horizon.
The road runs 48 miles from Estes Park to Grand Lake, typically open from late May through mid-October depending on snowpack. The Alpine Visitor Center at 11,796 feet is the highest visitor center in the National Park System — worth a stop for the views alone.
Tips for driving Trail Ridge Road:
- Allow at least 3 hours to drive it properly with stops
- Temperatures at the summit are 20–30°F colder than Estes Park — bring a jacket even in July
- Watch for elk, bighorn sheep, and marmots along the tundra sections
- Pull completely off the road at designated pullouts — stopping in traffic lanes is dangerous and illegal
- The road closes at the first significant snowfall, sometimes as early as September

Wildlife Viewing
RMNP is one of the best wildlife viewing destinations in the American West, and unlike many parks, the animals are genuinely visible without hiking deep into the backcountry.
Elk: The park’s most iconic residents. Herds of hundreds graze Moraine Park and Horseshoe Park meadows at dawn and dusk year-round. September and October bring the rut — bulls bugling and sparring is one of the great wildlife spectacles in North America and happens right along the road.
Moose: Head to Kawuneeche Valley on the park’s west side. Moose are regularly spotted in willow thickets along the Colorado River headwaters. Early morning is best.
Bighorn Sheep: Often visible on rocky slopes near Sheep Lakes in Horseshoe Park, especially in spring when they come down to lick minerals. The park holds one of Colorado’s largest bighorn populations.
Black Bears: Present throughout the park but rarely seen. Store food properly — bear canisters are required for overnight backcountry trips.
Marmots and Pikas: Abundant above treeline along Trail Ridge Road. Yellow-bellied marmots sun themselves on rocks near the Alpine Visitor Center. Pikas — small round mammals that look like a cross between a rabbit and a hamster — are vocal and active in rocky talus slopes.
Camping in Rocky Mountain National Park
Moraine Park Campground — the largest in the park with 244 sites, open year-round. Located in a beautiful meadow with elk frequently grazing nearby. Electric hookups available in some loops. Book 6 months ahead for summer weekends.
Glacier Basin Campground — 150 sites, tents and RVs, no hookups. Central location with easy shuttle access to Bear Lake trailhead. Open late May through September.
Aspenglen Campground — 52 sites near the Fall River entrance, quieter than the main campgrounds. Good choice for early-season visits when other campgrounds are still closed.
Longs Peak Campground — tents only, 26 sites, no reservations — first come first served. Primarily used by Longs Peak climbers doing pre-dawn starts. Basic facilities.
Timber Creek Campground — 98 sites on the park’s west side near Grand Lake, open late May through September. Less crowded than the east side campgrounds.
All reservations are made through Recreation.gov — most sites open for booking 6 months in advance, and summer weekends fill within minutes of the reservation window opening.

Where to Stay Near Rocky Mountain National Park
Most visitors stay in Estes Park on the east side or Grand Lake on the west side. Estes Park has far more lodging options and is closer to the most popular trails.
Estes Park (east entrance): Full range of hotels, motels, vacation rentals, and the iconic Stanley Hotel. 10 minutes from the Beaver Meadows entrance. Browse Estes Park hotels on Hotels.com | Vacation rentals on VRBO
Grand Lake (west entrance): A quieter, less-visited base with a charming small-town feel on the shore of Colorado’s largest natural lake. Better choice if you want to explore the Kawuneeche Valley and west side trails without the east side crowds. Browse Grand Lake hotels on Hotels.com
Lyons & Allenspark: Small towns south of Estes Park along Highway 7, sometimes cheaper and less crowded. Good base for accessing the southern trails like Longs Peak and Wild Basin.
Getting to Rocky Mountain National Park
From Denver: 1.5–2 hours via US-36 through Boulder to Estes Park (east entrance). Most popular approach.
From Denver International Airport: Add 30–45 minutes to the Denver estimate depending on traffic on I-70/I-270.
From Fort Collins: 45 minutes via US-34 through the Big Thompson Canyon to Estes Park.
From Grand Junction: 3.5 hours via I-70 east then US-40 north — enters via the west side at Grand Lake.
Entrances:
- Beaver Meadows (east, most popular) — on US-36 west of Estes Park
- Fall River (east, secondary) — on US-34 west of Estes Park
- Grand Lake (west) — on US-34 at the north end of Grand Lake
Parking: The Bear Lake Road corridor fills completely by 8–9am on summer weekends. Take the free park shuttle from the Estes Park Visitor Center or the Park & Ride on Bear Lake Road. Many trailheads now require reservations in addition to the timed entry permit — check nps.gov/romo before you go.
Visitor Tips
- Altitude: The park ranges from 7,860 to 14,259 feet. Acclimatize in Estes Park for at least one night before attempting strenuous hikes above 11,000 feet.
- Afternoon thunderstorms: Daily occurrence in summer, typically building by noon and hitting above treeline by 2–3pm. Start hikes early and be below treeline by early afternoon.
- Water: Bring more than you think you need. High altitude and dry air cause dehydration faster than you expect. Filter any stream or lake water — giardia is present throughout the park.
- Cell service: Essentially nonexistent inside the park. Download offline maps on AllTrails or Google Maps before leaving town.
- Pets: Allowed in parking lots, campgrounds, and along paved roads but not on trails. This is strictly enforced.
- Leave No Trace: The alpine tundra along Trail Ridge Road looks tough but is extremely fragile — a single footstep off trail can damage plants that took decades to grow. Stay on designated paths above treeline.
