Tony's #603 the Forest Service's write-up

season April to October

Tony’s Trail #603 begins at Verzuh Ranch Road and ends at an intersection with the Upper Loop Trail #435. It is close to town and connects you with other trails filled with aspen that hug Crested Butte Mountain. This trail starts with a gradual climb following switchbacks through sage brush where a variety of wild flowers can be enjoyed. It ends after about 0.7 miles when it reaches the Upper Loop Trail. There are beautiful views of Whetstone Mountain, the golf course The Club at Crested Butte, Lake Grant, and the town of Crested Butte from this trail. It’s especially colorful in the fall when the aspen leaves change color.

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.
