The Geologic Trail is a self-guided 1.2 mile (round trip) trail that that highlights over a billion years of geologic history of the Florissant valley. It passes over the ancient lake bed, crosses County Road 1, then ascends past the remnants of a massive pyroclastic flow, and ends at a scenic overview of the Florissant valley.

Pets Pets are not allowed on any trails at Florissant Fossil Beds. They are allowed, on a leash, in the parking lot, and adjacent picnic area in front of the visitor center.

The trail begins on a gravel, 6 foot wide section that is part of the Petrified Forest Loop. After about .1 miles on this section you'll come to the junction of the beginning of the Geologic Trail. From there, the trail ascends about 20 feet on a narrow trail and then descends 20 feet down again using wooden steps. Then the trail crosses a two lane county road and continues on a narrow dirt/rock trail until it comes to a foot bridge that has three steps on either side.

About these trails

The lines are the National Park Service's public trails layer, the trailheads and the waterfalls, views, peaks and historic places along them the Service's public points of interest, read 2026-10-14 and simplified for the map. The write-ups are the Service's own "things to do", unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the park's own site before you go.
