One night backpack with warm swimming holes and views of the Three Sisters, Mount Hood, Mount Jefferson, Mount Washington, and Tree Fingered Jack.
Begin your hike at the Lava Camp Lake Trailhead. The trail winds through a forest flush with hemlock and fir while opening up into black lava flows. Continue for a little over two miles until you reach North Matthieu Lake. This is your first stop. Go for a swim out to the little island and have a snack. Once you have gotten your fill, hike on until you reach the South Matthieu Lake. South Matthieu Lake is smaller, however it feels more open and North and Middle Sister loom in the distance. There are campsites located around the lake. Pick one and set up camp and go for another swim because this lake is much warmer. Prepare yourself some food and hike out on the PCT to get an amazing sunset view and watch the sun melt away behind Mount Hood, Mount Jefferson, Mount Washington, and Three Fingered Jack.
