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.
