Trail Information


Topaz Mountain and Wallace Gulch 4x4 trails wind their way up through the forested hillsides of North Tarryall Peak and Topaz Mountain on the south side of Lost Park near Jefferson, Colorado from Lost Creek to an altitude just over 11,300 feet and back down again. As you pass through the pine, fur and spruce forests punctuated by gorgeous green meadows, you are treated to occasional glimpses of the peaks of the Lost Creek Wilderness Area north and east, across the valley. On the way down Wallace Gulch, back toward Lost Creek, you encounter a relic of a bygone era as you come across the rusting carcass of an old pickup truck. Wildflowers are abundant in the spring and early summer while changing aspen grace the view in the fall. There are many opportunities for camping making this a great place for a peaceful weekend get-a-way.

An absolute blast in light snow! Beautiful, quiet, clean. Open as of 11-27-22, but looks like it could change any day now.

Better than expected. Not a ton of camp sites but enough to let us get away from the big camps on the easy route below.

The seasonal gate on lost park is now open, making these trails open and accessible. Reports of little to no snow on the trails.

Team Hyke ran this trail today, along with Bonis Creek, Banana Peel, and Ryan. No one else around, the day was beautiful, green, and running water. Got to love Colorado.
