Twin Lakes to Turquoise Lake

This scenic out-and-back route connects two of Colorado’s most iconic alpine lakes, Twin Lakes and Turquoise Lake, via a series of peaceful trails and dirt roads through the San Isabel National Forest. With gentle elevation changes, big mountain views, and opportunities to swim or camp lakeside, this is an ideal multi-day trip for backpackers looking for a quieter alternative to higher-elevation passes.

Start from Twin Lakes, heading northwest on the Colorado Trail (CT) / Continental Divide Trail (CDT). The trail gradually climbs through pine and aspen forest.

Continue west and then north as the Colorado Trail skirts the eastern slopes of Mount Elbert. After passing through lodgepole forest and meadows, you'll reach Halfmoon Creek Road. Cross the road and continue toward Turquoise Lake.

Eventually, you’ll reach the turquoise-blue waters of Turquoise Lake, a large reservoir framed by forest and distant peaks. There are several dispersed camping options near the shoreline or established campgrounds if you'd like amenities. After taking in the views, or a swim, turn around and retrace your route back to Twin Lakes.
Flora and Fauna
Expect to hike through dense aspen groves, conifer forests, and open meadows filled with wildflowers in summer. Deer, marmots, pika, and the occasional moose or black bear may make an appearance. Birds of prey are often seen circling above open ridgelines.

Camping & Permits

• Dispersed camping is allowed along much of the route; follow Leave No Trace principles.

• No wilderness permits required, but campfires may be restricted depending on conditions.

• If camping at Turquoise Lake proper, check with the Leadville Ranger District for campground availability or restrictions.

Water
Plentiful along much of the route, especially in spring and early summer, but always filter or treat before drinking.
Considerations

• While this route avoids high passes, it still stays between 9,000 and 10,500 feet, so acclimatization may be necessary.

• Afternoon thunderstorms are common in summer; plan to hike early and seek shelter when needed.

Best Season
Late spring through early fall. Snow may linger into June at higher points, and early snowfall is possible in September.
