Mount Teneriffe 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.

The Mount Teneriffe Summit Loop offers a diverse and demanding hiking experience, guiding you through dense ancient forests before opening up to dramatic, expansive views. You'll encounter the beautiful Teneriffe Falls early on, then tackle the challenging "Kamikaze Trail" with its steep scrambles over roots and rocks. The reward for your effort is a stunning 360-degree panorama from the Mount Teneriffe summit, showcasing the surrounding peaks and distant cities.

Prepare for a strenuous day on this difficult 11.5-mile (18.4 km) route, which involves 3925 feet (1196 metres) of elevation gain and typically takes around 8 hours and 55 minutes. Trekking poles are highly recommended for the steep sections and descents. While specific parking details aren't always highlighted, arriving early is often a good strategy for popular trailheads, especially on clear days when the summit views are at their best.

This loop is a fantastic option if you're seeking a substantial workout and spectacular scenery without the crowds often found on trails like Mount Si or Mailbox Peak. The abrupt transition from the secluded forest to the open, exposed peak is a notable feature, providing a truly dramatic reveal. Keep an eye out for local wildlife, as the rich biodiversity of the Pacific Northwest forest is a constant companion on this challenging adventure.
