Description

Trillium Lake Crag, also known as Mosquito Butte, is a small crag just around to the north side of Trillium Lake. At about 30' high, it doesn't hold the longest or most epic routes, or even the most aesthetically pleasing routes, but it does provide some fun, moderate, mostly sport climbing in a beautiful setting.

You can access most of the anchors from above, but beware of getting down to some of the lower ones. There are some trees, and even an extra bolt, to create tethers to access some of the lower anchors to set up top ropes.

Getting There

Turn off of hwy 26 in between Government Camp and the spit of 26/35, onto forest road 2656. There will be signs for Trillium Lake Campground and Day Use areas. Drive to the end of the road, where you'll reach the Day Use Parking Area. Hike on the Trillium Lake Trail North, around the lake. Near the Northeast corner of the lake, when you're near the marshy area, look for a climber's trail to your right. Take that for 5-10 minutes and you'll see the crag. Alternatively, there is a small pullout on the west side of Forest Road 2656 with room for two cars that will save you the $10 parking fee. This approach not only saves a few dollars, but shortens the hike by 5 minutes.
