An adventurous loop ride to Boulder Lake via Gunsight Ridge Trail.

Features -none-


This is a great loop ride with an out and back to start and end. You'll ride through rolling terrain, and past a scenic lake.


This version of the Boulder Lake Loop starts at Bennett Pass. Pedal east on USFS Road 3550 to the Gunsight Ridge Trail. Ride north on the trail, climbing to the Camp Windy connector.

Turn right here and enjoy a quick but short descent to Grasshopper Road.

Pedal east along the road to the top of Crane Creek. From here the ride drops into steep and rowdy descent through massive pine trees covered in light green moss. Although there are a couple of small drops to negotiate, this section of the route is mostly fast and straight-on downhill. About midway through, there's one quick respite before the descent transitions to a level traverse.

The trail then heads south crossing several small drainages and crossing a couple of small meadows. The forest continues to be fairly dense until reaching the intersection with Boulder Lake.

Turn right to follow the Boulder Lake Loop or stay straight to finish Crane Creek. From the intersection the route continues downhill until one last little climb to USFS Rd 4870. From the intersection with Crane Creek pedal across relatively flat trail to a bridge crossing Boulder Creek. On the other side get ready for continuous and steady climbing west toward Boulder Lake.

As you reach the shore, the grade flattens and you'll get a view through the trees. It's a beautiful spot with rocky cliffs surrounding three sides of the lake.

Get ready for more climbing as you grind your way up steep slopes above Boulder Lake. From here, the route alternates between easy and hard uphill sections while following the base of a ridge.

The final push comes after crossing some open and extended patches of scree and loose rock.

Boulder Lake Trail ends at Bonney Meadows Campground.

Stay right on Bonney Meadows Road to continue ride back to the bottom of Gunsight Ridge Trail. Stay left here to follow the route back to the beginning at Bennett Pass.

Great riding conditions. "Windy" connector still has a couple of downed trees when you branch off Gunsight, other than this the trail is clear.

LOTS of fallen trees across single track loop. Needs considerable clearing work to be rideable. 17.9mi

This route has you descending almost a thousand feet of gravel back to your car, who wants that? Park at bottom of Gumjuwac, ride hwy35 short distance to Pocket Creek, climb up to S end of Gunsight ridge, ride boulder lake as per this route, then ride Gunsight North, descend Gumjuwac for a rippin' descent right to your car!!

Its good and challenging trail, seems more like a hiking trail than MTB. I went long around the bottom of the Boulder Lakes and back up the west side (not the short route shown here to come back). Personally i would go the opposite direction on the long route for more downhill. No Matter, you're going to have to lift bike over down trees and push up some steep switchbacks. The long gravel down on the way back made me happy as I was exhausted. Jul 6, 2018
This route is barely maintained with a lot of blow downs and a gravel climb to/from Bennet Pass. If you have that one friend that loves to make nonsensical routes then this trail is for you. Aug 5, 2018
