| Devil’s Big Loop

Please read the Rules. This is an unsupported route. You need to be self-sufficient and are solely responsible for your actions.

The classic Tronsen Ridge / Devil’s Gulch loop just got bigger: by starting near Blewett Pass. This also means less driving if you are coming from the Seattle side. You’ll warm up by climbing a gravel road with great views of the Cascades. The first opportunity for single track is the Table Mountain trail, which you’ll ride via a couple other trails to the main event: the rowdy descent on Tronsen Ridge trail. A few punchy climbs will keep you warm here before it’s all smooth sailing down Red Hill trail. Afterwards, Red Devil and Devil’s Gulch will bring you back up to the ridge. From there, you’ll ride along the edge of the Mission Creek drainage on the Liberty Beehive gravel road. This small road with big views takes you to the last single track of the day: hike-a-biking up Mount Lillian which marks the highest point of the ride at 6100 ft. Unfortunately, the top is covered in trees, but a couple hundred feet down on your right is a meadow with an excellent view point. The Mount Lillian single track downhill is a bit rough, but nothing like Tronsen Ridge. Afterwards, you’ll head (mostly) down on gravel roads back to the start/finish, skipping the single track section from the beginning of the ride.

A lot of water is flowing in Mission Creek (along the Devil’s Gulch Trail). Naneum creek also tends to flow pretty well. No other sure resupply points are along route.

  3. Planning for this in June. Heading over from Boise, probably solo. Going to camp nearby, any CG recommendations? Can I pay the day use fee at the Trailhead? Looking forward to it, been wanting to ride this area for awhile now.
