Bear Lake and Trail Ridge Road are where most first-time visitors start and stop — and they’re beautiful, but they’re also where the crowds concentrate. This guide covers 25 hidden gems in the Rocky Mountains, most inside Rocky Mountain National Park itself, a few in the wider Colorado high country nearby, all chosen for alpine lakes, waterfalls, and trails that reward the extra effort to reach them. I walk through all of these in the video below, so start there for a visual preview before you plan your route.
What ties this list together isn’t just remoteness for its own sake — it’s the kind of scenery that Colorado’s high country does better than almost anywhere else in the country: glacially carved cirques holding impossibly clear water, wildflower meadows that peak for only a few weeks each summer, and mining-era relics scattered through terrain that’s barely changed since the 1800s. Some of these spots require a serious hike; others are a short walk from a trailhead. Either way, they all sit a step beyond the handful of destinations that show up on every first-time Colorado itinerary.

Waterfalls & Hot Springs

A turquoise, travertine-lined lake in Glenwood Canyon, fed by Bridal Veil Falls, and one of Colorado’s most distinctive hikes thanks to the mineral deposits that give the water its striking color. A permit system now limits daily visitors to protect the fragile ecosystem.
Glenwood Canyon. Permit required, booked in advance. Best in late spring for full water flow.

A backcountry hike near Aspen leading to natural hot springs at nearly 11,200 feet, one of the most rewarding (and most physically demanding) soaks in the state.

Scenic Drives & Iconic Views
23. Maroon Bells
The most photographed peaks in Colorado, the twin fourteeners of Maroon Bells reflect dramatically in Maroon Lake, especially at sunrise. A shuttle system limits vehicle access during peak season to manage crowds.

24. Crystal Mill
A 19th-century wooden mill perched dramatically over the Crystal River, one of the most photographed historic structures in Colorado, reached via a rough backcountry road near Marble.
Near Marble. Free to view; high-clearance vehicle recommended for the access road. Best in golden afternoon light.
25. Trail Ridge Road
The highest continuous paved highway in the United States, Trail Ridge Road climbs above 12,000 feet through RMNP, offering sweeping tundra views most visitors experience only from their car — worth a stop at one of its many overlooks.
Rocky Mountain National Park. Free with park entry; seasonal closures (typically mid-October to late May). Best midday when the road is fully open and clear.
Planning Your Visit
Timed-entry permits: Rocky Mountain National Park requires a timed-entry permit during peak season (roughly late May through mid-October) in addition to the standard entrance fee, especially for the Bear Lake Road corridor. Book online well in advance — permits for popular dates sell out.
Best season: June through September gives the widest trail access and mildest weather. Trail Ridge Road typically closes by mid-October and doesn’t reopen until late May, so shoulder-season visitors should check current conditions before planning a trip around it.
How many days to allow: 3-4 days lets you mix a couple of easier lake hikes with one longer trek like Sky Pond or Chasm Lake, plus a drive along Trail Ridge Road. A single day realistically covers only one or two major hikes given trailhead drive times and altitude.
Altitude: Many of these trailheads sit above 9,000 feet, and several lakes are above 10,000-11,000 feet. Give yourself a day or two to acclimate if you’re arriving from sea level, and start hikes early to avoid common afternoon thunderstorms at elevation.
Packing Essentials for Rocky Mountain Hikes
Layers: Mountain weather shifts fast — a warm, sunny trailhead start can turn into a cold, windy summit within an hour. Pack a shell layer even on clear days.
Sun protection: UV exposure increases significantly at altitude. Sunscreen, sunglasses, and a hat matter more here than they might at sea level, even on cool days.
Plenty of water: The dry mountain air and elevation both accelerate dehydration. Carry more water than you think you’ll need, especially on longer hikes like Sky Pond or Chasm Lake.
An early start: Afternoon thunderstorms are common in the Rockies through summer, particularly above treeline. Starting hikes by 7-8am gives you the best chance of summiting or reaching a lake before storms roll in.
