Protecting more than 300 acres of coastal habitats along the meandering, estuarine San Pablo River, Castaway Island Preserve is a breezy spot to get away from the city neighborhoods and enjoy a breath of fresh air outdoors.
A peninsula on the edge of suburbia, it’s its own world once you pass through the gates. Ibis and wood storks comb through the shallow marsh edges. Gopher tortoises lumber through the protected pine flatwoods of the island, which is surrounded by the estuary.
This is a gentle mile-long walk for all ages, well-interpreted and fun to follow – especially for kids – with plenty of benches and overlooks along the way.
