“A trail through the fields that provides opportunities to see wildlife, wildflowers and great views.”— David Hitchcock
Family Friendly It climbs gently through the preserve, where some of the best views of the San Francisco Bay come into view. The grasslands offer opportunities to see wildflowers and animals feeding in the evening.
The Serpentine Trail goes off to the right and drops down the hillside. The dirt track intersects with the Franciscan Trail at roughly .5 miles as shrubs begin to crowd in on the trail. Hummingbirds can be seen resting on bushes and animals can be seen feeding in the fields in the evening. The trail enters the woods and continues until it emerges from the trees at the Sylvan Trail intersection. In the woods, there are a couple of obstructed views of the San Francisco Bay, but the views open up at the intersection. The Sylvan Trail goes off to the left at this point, while the Serpentine Trail snakes its way up the hillside to the right. The trail is rougher and rockier in this .2 mile section that climbs to the Live Oak Trail, which cuts back to the right. Continuing straight ahead, the trail levels off until it meets up with the Sunset Trail and ends.
From this point, you can return to the trailhead via the Sunset Trail or use the other trails that have intersected with the trail along the way to explore other areas of the preserve.
Wildflowers can be seen along the trail in the fields, especially in the spring.
