Lion Lake #1 is located in the northwestern area of the Wild Basin of Rocky Mountain National Park, Allenspark, Colorado. Some of the surrounding destinations nearby are Lion Lake #2, Trio Falls, Castle Lake and Snowbank Lake.

From the Wild Basin trailhead, follow the Wild Basin Trail for 1.5 miles until you run into the campsite sign. Stay to the north on trail to the campsites. If you want to see Ouzel Falls and Calypso Cascades stay on the Wild Basin Trail, although this will add about .7 miles one way to the hike. Hike around 2 miles through the campsites until you arrive at the Thunder Lake/Lion Lake Junction. By taking the campsite shortcut, and a brief stop by Castle Lakes, we arrived at Lion Lake #1 in just under 6.5 miles.
There are a number of back country wilderness campsites in this area including: Pine Ridge, Tahosa, Aspen Knoll Llama, Siskin and North St. Vrain campgrounds.
Lion Lake trail is overall easy to follow, although there are several sections that were rocky with uneven terrain. In the summer you are greeted with sounds of running water and wildflowers all around the lake.
Lion Lakes Winter Access
During the winter and heavy snows, the road to the Wild Basin trailhead may be closed. This could add up to 6 miles round trip to your entire hike. For this reason hiking to Lion Lakes may be best suited in the summer months.
