Talus Loop Trail

The Mount Si and Mount Teneriffe Loop offers a comprehensive and rigorous exploration of the area, combining two iconic peaks into one challenging hike. You'll traverse old-growth forests, navigate steep switchbacks, and encounter the impressive Teneriffe Falls, especially beautiful in spring. The route culminates in expansive 360-degree views from both summits, showcasing Mount Rainier, the Puget Sound, and the Snoqualmie Valley.

This difficult 15.9-mile (25.5 km) loop demands endurance, with a significant 5962 feet (1817 metres) of elevation gain and an estimated duration of 12 hours and 26 minutes. Plan to arrive early for trailhead parking, as it can fill up quickly, especially on weekends. Be prepared for varied terrain, including rocky sections and the steep "Kamikaze Trail" on the Teneriffe side.

What makes this loop notable is its unique blend of the popular Mount Si with the more secluded Mount Teneriffe, offering a quieter experience on parts of the trail. While Mount Si can be crowded, the Teneriffe sections provide a wilder feel. This makes it a highly regarded adventure for those seeking a demanding day with diverse scenery and unparalleled panoramic viewpoints.
