Directions to Trailhead
This is a popular, family-friendly hike, but that doesn’t mean it’s not worth checking out. Lost Lake is a moderately easy hike that begins at the historic Hessie Townsite (an old mining town, high in the Rocky Mountains). This hike offers a lot of bang for your buck: not a lot work for a lot of great sights.

Route Description for Lost Lake Hike

Begin the Lost Lake Trail at the Hessie Trailhead where there is a map of the surrounding area. Follow the signs for Lost Lake, crossing over a bridge and onto a pretty trail through pine forests and aspen groves.

After a couple of switchbacks past an old log cabin, you will gain elevation alongside an impressive waterfall. A short side trail spurs off from the main trail to a waterfall overlook point that we think is worth the view!

Continuing on to Lost Lake, you will descend down into a small valley before crossing over a bridge to the base of a second, smaller waterfall. From this point, the trail climbs to the other side of the valley andall the way up to Lost Lake.

From the lake, you will enjoy views of Mt. Neva and Mt. Jasper off in the distance. Once you’ve had your fill of views, you can hike back the way you came.

I just want to say that the name of this hike was perfect. We did this hike year 2018 summer, and we almost got lost because there wasn't enough signage. It's good to see how things have improved btw.

Gorgeous combination of valley/mountain views, waterfall and lake. It’s steep in parts and the trail is rocky. Such a magical time!

Nice hike. The trail was mostly flat, aside from the slight incline as you get closer to the waterfall.
