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.

Willamette National Forest offers a diverse range of volcano hiking experiences. You can explore at least 9 distinct volcano hiking trails within the forest, catering to various skill levels.
The prime season for volcano hiking in Willamette National Forest is typically from late spring through early fall (June to October). During these months, trails are generally snow-free, and the weather is more predictable. Higher elevation trails, especially those around peaks like the Three Sisters or Mount Jefferson, may retain snow well into July.
While many volcano trails in the Willamette National Forest are challenging, some sections or shorter loops can be suitable for families. For instance, the Four in One Cone via Scott Trail offers a moderate option with unique volcanic features. Additionally, the Clear Lake Loop Trail, though not directly a volcano summit hike, provides a family-friendly experience around a lake formed by volcanic activity, where you can see ancient submerged trees.
Hiking in Willamette National Forest's volcanic regions reveals a fascinating array of geological features. You'll encounter expansive lava fields, ancient volcanic cones, and dramatic peaks like Mount Jefferson and the Three Sisters. Trails often traverse through forests that have grown on volcanic soil, and you might see evidence of past eruptions in the rock formations. The Tamolitch Blue Pool, where the McKenzie River reemerges through porous lava, is a striking example of the region's unique hydrology shaped by volcanic activity.
Yes, there are several excellent loop options that allow you to experience the volcanic landscapes without retracing your steps. The Scott and Obsidian Trail loop is a popular choice, offering stunning views and diverse terrain. Another great option is the South Matthieu Lake – Yapoah Crater loop from Lava Camp Lake, which takes you through beautiful alpine scenery and past volcanic formations.
Layering is key for volcano hiking in Oregon due to variable weather conditions, even in summer. Wear moisture-wicking base layers, insulating mid-layers, and a waterproof/windproof outer shell. Sturdy hiking boots with good ankle support are essential, especially on rocky or uneven volcanic terrain. Don't forget sun protection (hat, sunglasses, sunscreen) and plenty of water.

Hikers frequently praise the breathtaking panoramic views from the summits, the unique geological formations like lava fields and volcanic cones, and the sense of solitude found in the wilderness areas. The diverse landscapes, from lush forests to rugged alpine terrain, are also a common highlight.
Yes, permits are often required for hiking in certain wilderness areas within Willamette National Forest, especially during peak season. For example, the Three Sisters Wilderness, which includes many prominent volcanic peaks, typically requires a permit for both day use and overnight stays. It's crucial to check the latest regulations with the U.S. Forest Service before your trip, as requirements can change seasonally and by specific trailheads.
Many trails in Willamette National Forest are dog-friendly, but regulations vary, especially within designated wilderness areas. Always check specific trail rules before heading out. When dogs are permitted, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all hikers. Be mindful of volcanic terrain, which can be sharp and hot on paws, and ensure your dog has enough water.
For experienced hikers seeking a challenge, the Willamette National Forest offers several strenuous volcano trails. The Diamond Peak via Rockpile Trail is a demanding ascent to a prominent volcanic peak. Another significant challenge is hiking sections of the Pacific Crest Trail (PCT) that traverse through the volcanic landscapes of the forest, offering long distances and considerable elevation gain.
Yes, the Willamette National Forest is rich in water features, including numerous waterfalls, many of which are accessible from trails that also offer views of volcanic landscapes. Notable waterfalls include Sahalie Falls and Lower Proxy Falls. While not directly on a volcano summit, these are often found in areas shaped by volcanic activity and can be combined with other hikes for a diverse experience.
