Situated at just under 10,000 feet, High Creek Fen Preserve is an astonishing vestige of the last Ice Age. The preserve is the most ecologically diverse, floristically rich fen known to exist in the Southern Rocky Mountains, containing more rare plant species than any other wetland known in Colorado. It supports two rare plant communities and 14 state-rare plant species, most of which are isolated populations that survived here after the glaciers receded.

The fen is fed primarily by groundwater that is constantly flowing to the surface. Visitors can enjoy bird and wildflower watching, hiking, and other nature-based activities. High Creek Fen is a very boggy area with level terrain and no established trails.

Traversing the fen can be hazardous, and visitors should wear rubber boots or old shoes willing to be thrown away afterward. During summer months, deer flies are an issue; visitors should come prepared with long sleeves, pants and insect repellent. No pets are allowed at the preserve.
