The lava flows and cones in this area feel otherworldly. Views of North and Middle Sister are an added bonus.

South Matthieu Lake is much smaller than the north. It offers fantastic views of the North and Middle Sister to the south, surrounded by a beautiful alpine setting. If you want to extend your run, it is the last reliable water source for at least 15 miles northbound, or you can continue on the PCT, where the next water source is another few miles further.

The small crystal clear lake is an excellent place to stop and take memorable photos. The lakeshore is heavily wooded, with rainbow trout regularly stocked by the State of Oregon, which is a draw for anglers. Water flows in and out of the lake under the porous lava soil.

Four-In-One Cone, a remarkable formation, unites four distinct cinder cones into a .4-mile-long ridge. Captain Felix Scott's 1862 trailblazing journey inspired this hike along the Scott Trail, leading to a captivating viewpoint atop the crater rim.
