Trail Overview

The route begins on FS 120C at the juncture with Redcone and Webster Pass. Head towards Hall Valley campgrounds and Gibson Lake. The route passes through lots of pine and aspen groves on a rocky road requiring 4WD. There is a stream crossing towards the beginning section of the trail around 8 inches deep. Rocks vary in size up to 8 inches until the very last dispersed camping spot with a sign marking it as the 20th dispersed camping spot. From here, the road forks. To the right, the trail deadends after another half mile at a gate with radioactive hazard signs stating to stay out. This section does offer beautiful views. Then to the left, you can continue on toward the Missouri Mine. This section is the most difficult, with lots of willows, off-camber pitches, and rock obstacles over 12 inches' requiring high ground clearance.

Difficulty

Most of the trail is between a 2-3 and very accessible for small overland trailers. After camping spot number 20, the route is narrow with larger obstacles and tight turns. Do not take a trailer past campsite 20, as there's no place to turn around.

Trail is fine until the last Est. 4 miles, then the snow is knee deep, passable as I made it in 4 low with my lockers off

Nice, short little trail for a sxs. Small rock gardens and some small obstacles. Fall colors are definitely past peak but was a beautiful day. Red Cone, Radical and Webster were seriously crowded - spent a lot of time in park on Red Cone waiting on a line of 10-12 jeeps and Tacomas. Parking at the top of Webster was full.

Maybe a foot deep water crossing and 50 minutes of heavy hail. Downed tree maybe 200 yards pass the Gibson Lake Trail and if you get to it like we did, you will be reversing at least 60 yards over a couple of rocks until you can turn around.
