One of the newest bay trails is in Novato at Hamilton. I have not scouted this out so it is a exploratory walk. According to my Bay Trail Maps there is 2 miles of levy-top trail accessed via the Reservoir Hill Trail. Plan is to meet at 10:15 at the trail head.
Walk will be around 4 miles. I will have map my walk app on and we will turn around near 2 miles. I do not know if there is bathrooms at the trailhead so plan accordingly.
Heavy rain may cancel, as of now Tuesday looks dry and in the 70s. Directions from 101, take Bel Marin Keys exit. Cross over 101 to the east side, turn right on Nave Blvd, continue south on Nave Drive to North Hamilton Parkway, continue 1/2 mile Reservoir Hill trail is on the left.
I plan to bring a lunch to eat before the drive home.
