Cayton Trailhead the Forest Service's write-up

No fee · reservation required

The Cayton Trailhead is located 20 miles south of Silt in the West Divide region of the Rifle Ranger District. The trailhead features the historic Cayton Ranger Station and provides access to Cayton Gulch Trail and Lake Fork Trail.

The Cayton Ranger Station is named for James Grimshaw Cayton, who was one of the nation’s first forest rangers. The Ranger Station is the second oldest building of its kind in the United States, having been built in 1910. James Cayton and his wife Birdie (a school teacher) built the cabin and were the first individuals to live in the structure. In addition to serving as James and Birdie’s home, the station functioned as the headquarters for managing what was then known as the Grand River Ranger District on the Battlement National Forest. James and Birdie conducted a variety of official activities while living and working at the Ranger Station, including: surveying boundaries, posting signs, building and repairing telephone lines, inspecting homestead claims, monitoring ranchers’ cattle, selling hunting licenses, and looking after the station’s garden and livestock.

The Cayton Ranger Station was added to the National Register of Historic Places in 2005. Today, visitors can interact with and learn about the Station in a variety of ways. Visitors can take a hike up Cayton Gulch, explore the grounds, or enjoy a picnic near the Station. Visitors can also look inside the interior of the cabin, which is still decorated as it appeared when James and Birdie lived on site. Interpretive brochures and posters available outside the Station provide information about the lives of James and Birdie, as well as the history of the structure.

The Forest Service manages this site in partnership with the Cayton Ranger Station Foundation. The Station is available for special events, and the Foundation also periodically hosts interpretive programming on the grounds.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, 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 forest's own site before you go.
