From the Fern Lake Trailhead, the hike to The Pool is around 3.4 miles round-trip with 205 feet of elevation gain. This trail runs along the Big Thompson River, and offers great fishing opportunities - just be sure to familiarize yourself with fishing regulations. Along the trail you will find plenty of shade as well as blooming wildflowers throughout spring and summer.

Storm Warning: Weather in Colorado can turn in an instant! Be prepared for changing weather conditions. Check the forecast before heading out. Lightning can strike anywhere in Rocky. Watch for building storm clouds and return to the trailhead immediately if you hear thunder. As a rule of thumb, try to be back at the trailhead by noon.
