Fern Lake Trail

The Fern Lake Trail in Rocky Mountain National Park, Colorado, runs 4.8 miles (7.7 km) from Moraine Park in the eastern part of the park westward to Fern Lake, the first portion of the trail following the course of the Big Thompson River. The trail was first informally established in the late 1880s as a way to get to "The Pool," a wide spot in the Big Thompson where a small lodge predated the 1915 establishment of the park. The trail was improved by the Estes Park Protective and Improvement Association between 1907 and 1912, with a new bridge at The Pool. Two years later the trail was rebuilt to maintain no more than a 10% grade and to provide better access to Fern and Marguerite Falls. In the 1920s Fern Lake became a popular winter destination for skiing, complete with a lodge. From 1933 the trail was rebuilt over three years with Civilian Conservation Corps labor, building retaining walls and adjusting the trail's alignment.
