Hike The Hidden Trails of Rocky Mountain National Park

Here's a detailed hiking planner that will take you to the hidden corners of Colorado's most scenic park.

Expedition Planner


The Tonahutu Creek/North Inlet Loop begins near the Kawuneeche Visitor Center by Grand Lake. The Never Summer Loop begins at the west end of Trail Ridge Road, just north of Grand Lake. (Note: Trail Ridge Road usually opens around Memorial Day; western access is from I-70 then over Berthoud Pass). The Lost Lake, Mummy Range hike begins at the North Fork/Dunraven trailhead.


Even on these uncrowded trails, if you want a specific campsite (especially on the Tonahutu/North Inlet Loop), you better reserve early. The jockeying begins March 1. If you’re flexible on campsites, you can often get a permit the morning of your hike from the backcountry office in Estes Park or the Kawuneeche Visitor Center.

Special conditions

These trails are high (they begin above 8,000 feet). If you’re a lowlander, allow a few days to adapt to the altitude. Snow doesn’t melt off the highest passes until July, right about when the

infamous afternoon thunderstorms kick in. Be sure to check on storm patterns, so you don’t get caught above treeline when the lightning bolts start flying.
