Larimer County open spaces: free naturalist-led field trips that home school groups can request

Larimer County Natural Resources runs naturalist-led field trips at three county open spaces: Devil’s Backbone, River Bluffs and Horsetooth Mountain. There is no charge. The county says it is happy to lead a trip for a scout troop, camp, youth group or home school.

Field trips are available Tuesday through Friday, starting at 9 or 10 a.m., and are typically scheduled during the spring and fall semesters. The county asks for at least two weeks of notice and prefers a month. Its special request page adds that naturalists can lead guided hikes for groups including homeschools, and that most of those programs run about three hours.

A note for homeschool families: the trips were built around classroom lessons by grade, so a co-op with mixed ages should say so when it requests a date. Group size limits apply; the county’s page lists about 100 people for its station-based trips.
