Summer in Estes Park is pure mountain magic: wildflowers, long sunny mornings, afternoon thunderstorms that roll through and clear out, and cool evenings perfect for a fire pit. It's also our busiest season, so a little planning goes a long way. Here's how I tell my guests to make the most of it.
First, plan your park entry
Rocky Mountain National Park uses a timed entry reservation system in summer. In 2026 it ran from May 22 through mid-October:
- Timed Entry (most of the park, including Trail Ridge Road) is needed from 9 a.m. to 2 p.m.
- Timed Entry + Bear Lake Road is needed from 5 a.m. to 6 p.m. for the Bear Lake corridor.
Reservations are made only on Recreation.gov and cost a \$2 processing fee, plus your park entrance pass. Extra reservations are released at 7 p.m. MT the night before. My best tip is to go early: if you enter before 9 a.m., you don't need a timed entry reservation for most of the park (not Bear Lake Road). My timed entry guide covers the details.
Drive Trail Ridge Road
Trail Ridge Road is the highest continuous paved road in the United States, topping out at 12,183 feet. The views over the tundra are unforgettable. Stop at the Alpine Visitor Center (11,796 feet, the highest visitor center in the National Park Service) and bring a jacket; it can be 20+ degrees colder up top. The road usually opens around Memorial Day weekend (May 29 in 2026).
For adventurous drivers, Old Fall River Road is a one-way, uphill, unpaved scenic drive that typically opens in early July. Vehicles over 25 feet and trailers aren't allowed.
Hike to an alpine lake
Summer is prime hiking season. Easy favorites include Bear Lake, Sprague Lake and Lily Lake, and Alberta Falls is a lovely short waterfall hike. Start early: afternoon lightning is common in the Rockies in summer, and you want to be off exposed ridges by early afternoon. See my easy hikes guide for distances.
★★ Jeff & René's top pick: Sky Pond is our all-time #1 hike, and summer and fall are the seasons for it. It's strenuous but absolutely spectacular: 4.9 miles one way with about 1,710 feet of gain from the Glacier Gorge Trailhead, past Alberta Falls and The Loch to a high-alpine lake ringed by sheer rock walls. Start early, since parking fills fast, and you'll need the Timed Entry + Bear Lake Road reservation in season. It's not an easy hike, so save it for a day when you're acclimated.
Ride the Estes Park Aerial Tram
The Aerial Tram carries you up Prospect Mountain for big views of town and the Continental Divide. Its website lists the 2026 season as daily from May 9 to Nov. 1, weather permitting, and it pauses for lightning or extreme winds.
Enjoy Lake Estes
The 3.75-mile paved Lake Estes Trail circles the lake and connects toward downtown. It's great for a morning walk, a bike ride, or a stroll with your leashed dog. The marina area is a fun spot for families.
Fishing at Trout Haven (perfect for little kids)
If you have little ones, Trout Haven Fishing Pond (810 Moraine Ave.) is super fun. It's a stocked trout pond where kids have a great chance of catching a fish. No license, gear or experience is needed; you rent a pole and they hand you bait. Just know that every fish is catch-and-keep (no releasing), so be ready to take your catch with you. They'll clean it for you for a small fee. Check their open days and hours before you go.
Go horseback riding
A guided trail ride is a classic summer experience. Hi Country Stables at Glacier Creek, near Sprague Lake, is the only stable inside Rocky Mountain National Park, and its rides include park and Bear Lake corridor access. Jackson Stables at YMCA of the Rockies offers beginner-friendly rides into the park and pony rides for kids 5 and under. Book ahead in summer.
Stroll the Riverwalk and downtown
Downtown Estes Park and the Riverwalk are lively in summer, with shops, ice cream, taffy and patios. Parking fills up midday, so walk or use the town's shuttles when possible.
Wildlife watching
Early mornings and evenings are the best times to see elk, deer and bighorn sheep. Sheep Lakes in Horseshoe Park is a well-known spot for bighorn sheep. Always keep at least 75 feet away from elk and bighorn, and 120 feet from bears, moose and mountain lions.
Play Bluebell I Spy!: Pick up our Bluebell I Spy! Estes Park & RMNP game at the house and see how many of the 50 items your crew can spot this summer, from a hummingbird and a Steller's jay to a pika on the tundra and a rainbow after an afternoon storm. Locals also post daily sightings in the "Elk of Estes Park" Facebook group, so join before your trip.
Summer tips from your host
- Sun and altitude: UV is intense at elevation. Sunscreen, hats and plenty of water are a must.
- Afternoon storms: Plan big hikes for the morning.
- Layers: Mornings can be chilly even in July.
Evenings at Bluebell: those cool summer nights are made for the propane fire pit out back, and every stay comes with a s'mores kit. Sunset, toasted marshmallows and maybe a deer wandering past the back deck: that's summer at Bluebell.
