Emerald Lake Trail (Rocky Mountain National Park) Hiking Guide
The walk from Bear Lake to Emerald Lake strings three lakes together in under two miles: Nymph, Dream and finally Emerald, tucked under the walls of Hallett Peak and Flattop Mountain at the head of Tyndall Gorge. It is probably the most-hiked trail in Rocky Mountain National Park, and parking is the real challenge. Here is how far it is, what each lake offers, and how to get there.
Permit: Rocky Mountain National Park requires an entrance pass at every hour of the year: $30 per private vehicle for one day or $35 for 7 days, $25 or $30 per motorcycle, $15 or $20 per person on foot or bike (16 and older), the $70 park annual pass, or an America the Beautiful pass. Non-US residents 16 and older pay an extra $100 each unless entering on an annual or America the Beautiful pass. Entrance stations take cards only. From late May to mid-October you also need a Timed Entry + Bear Lake Road reservation to drive onto Bear Lake Road between 5 a.m. and 6 p.m. (May 22 to October 18 in 2026); it costs a $2 Recreation.gov fee per vehicle. No permit is needed to hike to the lakes.
Three Lakes in Under Two Miles
AllTrails lists the out-and-back at 3.3 miles with 662 feet of gain, about one and a half to two hours. The park puts Nymph Lake 0.5 mile from the trailhead, Dream Lake 1.1 miles and Emerald Lake 1.7 miles one way. Its climb figure for Emerald is higher, 771 feet on its Bear Lake Road page, while an older park list says 605. Add the short Bear Lake circuit at the start and AllTrails' combined route comes to about 4 miles.
What You See Along the Way
Each lake frames a different view of Hallett Peak and Flattop Mountain, and the trail ends at Emerald, the highest of the three. Summer brings columbine and other wildflowers near Dream Lake, and AllTrails notes that elk and pikas both show up along the route. Just before Dream Lake a signed fork heads left to Lake Haiyaha, which makes an easy extension. The park replaced the Dream Lake outlet bridge in fall 2025.
Parking at Bear Lake
The road ends at a large lot at 9,475 feet, and the park says it is often full by 9 a.m. in every season. In summer and early fall the free Bear Lake shuttle from Park & Ride is the stress-free option; from Estes Park itself there's a Hiker Shuttle that needs a $2 reservation per group of up to four. Driving up yourself between 5 in the morning and 6 at night, late May to mid-October, takes the corridor version of the park's timed-entry permit.
Mud, Snow and Ice
In late August rangers reported the trail dry to Nymph Lake but wet and muddy around Dream Lake and above it. From late October to early June the park says to expect snow on the Bear Lake trails and strongly advises traction devices and waterproof boots, so a winter walk here means microspikes. The route stays popular year-round because it's short, but snow hides the edges of the trail above Dream Lake.
Hiking tips for Emerald Lake Trail (Rocky Mountain National Park)
- Arrive before the lot fills around 9 a.m., or plan on Park & Ride and the shuttle.
- Bring microspikes from late October onward; the trail is packed snow for months.
- Add Lake Haiyaha from the fork below Dream Lake if you want a quieter second destination.
- Expect mud near Dream Lake after rain and wear shoes that can handle it.
- Leave pets at home; dogs aren't allowed on any trail in the park.
