  • Heron’s Head Park

    A nice easy out-and-back, great for birds, kids, and leashed dogs. White-crowned sparrows go crazy in the bushes while, in winter, the Bay fills up with migratory waterbirds.

This is Roy's Redwoods preserve, a 377-acre park that's been home to a ranch, a commune, and even Ewoks for […]
