If you’re a dog, you can thank your lucky stars for the opportunity to live in or visit Marin County, where dog-friendly open space abounds. In the beach department, leash-optional Muir Beach, Rodeo Beach, Bolinas Beach and Dillon Beach are tail-wagger faves. But for sheer scope of views, sense of remoteness and tingle of history (Sir Francis Drake slept here), Point Reyes National Seashore takes top bone. Dogs are required to be leashed on two-mile-long Limantour Beach and on more remote Kehoe Beach, which requires a half-mile hike-in over a series of sand dunes.
