8889 Sir Francis Drake Blvd., Lagunitas
With a dearth of freshwater swimming spots in the Bay Area, seekers of the aquatic will go to great lengths to discover a hidden watering hole. One of those gems is the Inkwells, a small group of pools located off Sir Francis Drake Boulevard in Lagunitas, in Marin. The legality of the spot is highly questionable, as it's surrounded by "No Parking" signs and there is no mention of it on any official maps or guides. Patrons have to park in town and make about a mile walk to the tucked-away lagoon, but the trip is worth it. The water is refreshingly cold on a summer day, and all the local kids entertain with some seriously irresponsible jumps designed to freak out squares from the city. We once saw a chubby 12-year-old cannonball 25 feet into a tiny pool of water. We were expecting carnage, but when he came up, there were only smiles.
