Triangle Lake Horse Camp is located on the south end of Triangle Lake in the Olallie Scenic area. While the lake is not visible from most camp sites, it is just a short walk or ride down the hill. This campground offers tranquil sites in a setting of lodgepole pines and mountain hemlocks. Long gravel parking pads accommodate both camp vehicles and horse trailers. A variety of trails are open to horse riding.  Other recreational activities include fishing and hiking.
