The Schilling Lake Trail offers a surprisingly diverse and tranquil hiking experience packed into a short distance. You'll wander through sun-dappled oak and madrone forests, transitioning into lush, cool redwood groves before reaching the serene, marshy Schilling Lake. This easy 1.6-mile (2.6 km) route, with just 113 feet (34 metres) of elevation gain, can be completed in about 41 minutes, making it an ideal quick nature escape.

Located in Thornewood Open Space Preserve, the trail begins with a moderate incline from the parking lot before leveling out. It's generally less crowded than other local trails, offering a peaceful outing. While the trail is family-friendly, be mindful of poison oak in the area and the potential for mountain lion sightings, as with any wilderness area. Visiting after winter rains can reward you with vibrant wildflowers.

This trail is a fantastic example of the diverse ecosystems found in the Santa Cruz Mountains, showcasing a rapid shift from dry hillsides to damp redwood forests. You can extend your adventure by connecting with the Bridle Trail for a longer, roughly 3-mile out-and-back hike along Dennis Martin Creek. The preserve also offers occasional panoramic views of Stanford University and the South Bay from higher vantage points.
