Part of the U.S. Fish and Wildlife Service’s San Pablo Bay National Wildlife Refuge, the Tubbs Island Trail offers views of the San Pablo and Greater San Francisco Bays and surrounding ridgelines and peaks. The trail starts near the intersection of Hwy 121 and Hwy 37 near Sears Point on the south side of 37, follows Tolay Creek, and splits for a loop around Lower Tubbs Island. The total trail length to complete the loop and back is approximately 8.15 flat miles with minimal elevation gain/loss.
Birdwatching is often best at low tides. Check the tide chart for San Pablo Bay.
As of 8/23/13, a 12 foot portion of the loop trail levy has been washed out, making it currently impossible to complete the loop trail. The washed out segment is approximately 150 yards west of the loop junction. Check with the Fish and Wildlife Service for the most up to date conditions.
Trails may be seasonally closed due to flooding/tides – check the condition of the levees with the Fish and Wildlife Service. It can also be very muddy immediately after a rainstorm, making biking or hiking impractical and/or impossible.
