The Cultus lake trails are shown as a singletrack loop, but could be done as an OAB from the Cultus Lake campground, extending the ride time and avoiding the fireroads.
These campground trails can be ridden in either direction, and best to avoid busy high summer weekends when the campgrounds (and trails) are full.
Cultus Lake is near the Sisters Wilderness Area, so Many Lakes Tr15, Metolius-Windigo Tr99 and Winopee Lake Tr16 are off limits to biking, beyond the lakeside segments of these trails.
Little Cultus Lake can also serve as the trailhead, which results in a slightly inverted ride profile and an easy end-of-ride road climb.
Metolius-Windigo Trail 99 is rideable outside of wilderness areas, so watch trail signage if exploring various sections of that great trail system.
Area Hiking: The Cultus Lake CG can serve as a basecamp for several hikes into the surrounding old growth forest, using Metolius-Windigo Trail 99 to hike towards Lava Lake, or Winopee Lake Tr16 to connect to Pacific Crest Tr2000-E.
Corral Swamp Tr8 and Benchmark Butte Tr8.5 offer some shorter day hike options.
Snowshoe Lakes Tr33 can be combined with Winopee Lake Tr16 into a full day loop option.
Mosquitoes are ferocious in this area until August. Feel free to try the natural repellents, and avoid drinking carbonated drinks prior to riding, but Deet 100 may be the only protection from 'the swarm'.
