The Woodland Outdoor Wanderers’ will enjoy this 3.6-mile Mare Island San Pablo Bay loop trail hike near Vallejo. Generally considered an easy route. It is a popular trail for birdwatching opportunities and beautiful water views. You'll need to leave pups at home — dogs aren't allowed on this trail.

Bring sturdy shoes, water, a hat, sunscreen, tick protection, and a snack. There will be plenty of time after the hike to explore the Mare Island Naval Shipyard Historic Park. Mare Island became the first US naval base on the West Coast in 1854. 

Of particular interest is St. Peter’s Chapel, the oldest Navy Chapel in the nation (built 1901). Soak in the brilliance of the Chapel, including the stained-glass collection, which includes 25 windows by the Tiffany Studios.

Hikers will gather at the Woodland Presbyterian Church, 1324 Columbia Drive, at 8:00 a.m. for an 8:15 a.m. departure, following sign-in, a hike overview, and carpooling arrangements. Directions will be provided for the 75-minute drive.

The Woodland Outdoor Wanderers is a community-based organization open to all, and dedicated to introducing Yoloans to their natural and cultural environments, and to each other.  For more information  email kathyjtrott@gmail.com
