Emerald Lake

The trail gains elevation steadily, reaching Nymph Lake after about half a mile, then continuing to Dream Lake, one of the most photographed spots in the park, where the water reflects Hallett Peak and Flattop Mountain. From there it climbs a bit more to Emerald Lake at the head of the valley.

Each lake has its own character, and the way the trail strings them together means the scenery keeps changing and improving as you climb. Wildflowers line the trail in summer, and the whole route is classic subalpine Colorado.

The round trip to Emerald Lake is roughly 3.5 miles with a moderate climb, well within reach of most reasonably fit hikers, though the high elevation makes it feel harder than the distance suggests. It typically takes a few hours at a relaxed pace with stops at each lake.

Because it starts at the busy Bear Lake trailhead, parking fills early and many hikers use the park shuttle. Snow and ice can linger on the upper section into early summer, so checking conditions and carrying the right footwear is wise.

The hike to Emerald Lake in Rocky Mountain National Park is a classic moderate day hike of about 3.5 miles round trip, starting from the popular Bear Lake trailhead. It climbs steadily, passing two other beautiful alpine lakes, Nymph Lake and the much-photographed Dream Lake, before reaching Emerald Lake in a rocky basin beneath the sheer face of Hallett Peak. The green-tinged water and dramatic mountain backdrop make it one of the most scenic and beloved hikes in the park. The relatively short distance combined with spectacular high-country scenery is why it is so popular, especially on summer days.

The Emerald Lake hike is considered moderate. At about 3.5 miles round trip with a steady but not extreme climb, it is achievable for most reasonably fit hikers and even many families, though the high elevation, starting around 9,500 feet and climbing higher, makes it feel more strenuous than the distance alone suggests. Take your time, drink plenty of water, and allow a few hours. Snow and ice can linger on the upper part of the trail into early summer, so proper footwear and traction may be needed early in the season. Checking current trail conditions before setting out is a good idea.

The trail to Emerald Lake begins at the Bear Lake trailhead on the eastern side of Rocky Mountain National Park, reached via Bear Lake Road from near Estes Park. Because the Bear Lake parking lot is small and fills very early, many hikers ride the park's free shuttle from the Bear Lake Park-and-Ride. During the busy season, the park also uses a timed-entry reservation system for the Bear Lake corridor. So it is important to check current shuttle and reservation information before your visit, and to arrive early or plan around the shuttle to secure access to this popular trailhead.

The Emerald Lake trail is really a tour of three alpine lakes. First you reach Nymph Lake, a small lake often dotted with pond lilies, about half a mile in. Continuing upward, you come to Dream Lake, one of the most photographed spots in Rocky Mountain National Park, where the water beautifully reflects Hallett Peak and Flattop Mountain. Finally the trail climbs to Emerald Lake itself, set in a rocky basin at the foot of Hallett Peak. Each lake is lovely in its own way, and stringing them together on one moderate hike is a big part of what makes this route so rewarding.
