Picture-perfect mountain lakes, rocky peaks, and quaking aspen are scattered throughout this popular, 3.7-mile out-and-back in Rocky Mountain National Park. Accessible in any season, this trail begins at the Bear Lake Trailhead, one of the busiest areas in the park. The trail travels across moderately flat terrain, with a 660 foot elevation gain.

From the Bear Lake parking lot, cross a wooden bridge, then turn left at the first trail junction. At the next Y-junction, stay right and follow the sign for Nymph Lake, Dream Lake, and Emerald Lake. The trail is paved for the first half-mile to Nymph Lake, the smallest of the three lakes. Catch a glimpse of Chaos Canyon and Otis Peak before walking through dense pines to Dream Lake, a finger-shaped lake bordered by craggy peaks.

From here, the route leads back into the forest for a rolling stretch of trail that drops onto the shores of Emerald Lake, a picturesque tarn at the foot of Hallet Peak and Flattop Mountain. Stay for lunch, then reverse your route to return to Bear Lake Trailhead.
