Thunder Lake

Trailhead: Wild Basin
Distance: 6.2 mi
Elevation Change: 2,074'

The trail follows North St. Vrain Creek for quite a while. Take the campsite shortcut to save some distance (although this means bypassing Calypso Cascades and Ouzel Falls). After the shortcut regains the main trail, it leaves creekside and climbs through the forest. At the Lion Lake trail junction, keep left. Just before arriving at Thunder Lake, the trail descends a bit. You've arrived when you see the hitching post and then the patrol cabin.
