Hiking
The Pinnacle Peak Loop Trail offers a fantastic, varied hiking experience, starting with a steady climb through a beautiful dense forest. As you ascend, the scenery opens up, culminating in stunning panoramic views from Pinnacle Peak itself, where you can see Mount Rainier, the Cascade Range, and the Green River Valley. The trail features natural dirt, gravel, and some rocky sections, with concrete steps on the steepest parts, providing a good challenge for its relatively short length.
This easy 3.4-mile (5.5 km) loop gains 945 feet (288 metres) in about 1 hour and 50 minutes, making it an excellent choice for a rewarding workout without a full-day commitment. Parking is available at the trailhead, but it's a popular spot, so plan to arrive early, especially on weekends. While generally accessible, checking for winter conditions is wise, as steep sections can become slippery.
Pinnacle Peak is a 335-acre volcanic cone, locally known as Mount Peak or Mount Pete, with a rich history of preservation. At the summit, you'll find unique columnar basalt formations and old concrete footings from a former fire lookout, adding an interesting historical and geological layer to your hike. It's considered one of the quickest peaks to "bag" near Seattle, offering big views for a moderate effort.
