Parking & Trailhead Information for Lost Lake Hike
Directions to Hessie Trailhead
At the roundabout in Nederland, Colorado, drive south onto CO-119/South Bridge St. Take a right onto Eldora Road which will take you to Elodora Colorado. The road continues through Eldora, and changes to Eldorado Road. It proceeds out of town and changes its name to Hessie Road. About 3/4 of a mile outside of Eldora, the road will split, 4th of July Road goes to the right, and Hessie will turn to the left. The 2WD Hessie Trailhead Parking area is at this split. Do not park alongside the road, as you will likely be fined. If the parking area is full, then go back to Nederland for the shuttle (weekends and holidays). There is parking for 4WD vehicles further up the dirt road and closer to the beginning of the official trail. It’s important to know that rains can quickly flood this segment of Hessie Road.
The Hike: Lost Lake Trail
If taking the shuttle, it will drop you off at the 2WD parking area. From here, hikers will follow a trail for that runs along the north side of the 4WD dirt road. The trail runs past a small pond and will keep to the right-side of the 4WD Hessie Trailhead road until it arrives at the official trailhead. Keep your eyes peeled for Moose who frequent these waterlogged meadows along this lowland segment of the trail. At approximately 1/2 mile from the shuttle drop, a sign marks the site of the old mining town of Hessie, Colorado.
Soon, the trail will cross the North Fork of Middle Boulder Creek via a footbridge and a large sign will map and describe the several trails and destinations that can be accessed from this point. Hikers will continue on this old mining road as it leads uphill towards both Lost Lake and the intersection for the trails that lead to Devil’s Thumb Lake, Jasper Lake, Woodland Lake, King Lake, and Bob and Betty Lakes. This trail profile will describe the route to Lost Lake only.
The next 1.2 miles climbs by way of switchbacks over rocky and steep terrain. Wildflowers pepper the trailsides and the riparian zone along Middle Boulder Creek. At the first trail intersection (Devils Thumb and Devils Thumb Bypass Trails), a sign will mark the way to Lost Lake and give distances and point the direction to the other destinations. Here the trail to Lost Lake will go left and cross another footbridge. Soon, a waterfall and set of cascades will come into view. The trail will make its way to a second intersection and sign. Here, the trail for Lost Lake departs, once again, to the left.
From this point, Lost Lake is just 1/2 mile away. It’s a steep segment but worth the views when you arrive. At Lost Lake, hikers can explore the outside circuit of its shores (this will add both time and distance to the hike). Return via the same trails.
