Campgrounds at Horsetooth Reservoir are already full for the July 4 weekend and almost full on other weekends in early summer. Reservations can be made up to 180 days in advance, so many of Larimer County’s most popular campsites are already full through early July at all campgrounds.

In addition to tent and RV campsites, Larimer County offers camper cabins at Horsetooth Reservoir and Hermit Park, an Airstream trailer at Horsetooth Reservoir and tipis at Flatiron Reservoir.
