Get a new perspective! Take a docent-led, 9-mile bicycle tour along the levees of the Don Edwards SF Bay Refuge. Learn about the Salt Pond Restoration Project and see Silicon Valley from a new angle. It’s nature in the middle of it all! The trail is level and smooth, but unpaved, and it can be windy. The tour starts and ends at the Alviso Marina County Park. The pace is moderate with stops. Helmet and water recommended. Recommended for ages 14 and over. Rain cancels.
