The lake was formed about 20,000 years ago when rising magma-encountered groundwater resulting in violent steam explosions. The resulting explosions formed a broad shallow crater, which later filled with water. The lake covers an area of 99 acres with average depth of 33 feet with a maximum depth of 58 feet. South Twin Lake is a lure's toss from the Deschutes arm of Wickiup Reservoir and less than a mile south of North Twin lake. Motorized boats are prohibited on this body of water. For boat launch information see South Twin Day Use .
Not a huge campground, easy access to South Twin Lake which is a premier lake for kayaks, paddle boards as powered boats are not allowed. Hard to find anything randomly showing up as I think you have to reserve everything online now. Right next door is a resort that you can walk in and check out the little store along with restaurant. You can even eat lunch on the patio right on the lake. There is also about a 1 mile trail that goes around the lake.
Campground close to lake. Plenty of sites. Camp Store within walking distance w restaurant as well. Water recreation rental available as well. Nice hikes available including one around the lake!
The site is located between the reservoir and south twin lake. Great location, easy access to water, fishing.
