Let’s imagine the rain stops, the sun reappears and you are ready to finally start summer. It’s hard to think of a more perfect spot than the Inkwells, a series of small, deep, dark, swimmable pools cascading into each other amid redwood groves in West Marin. Head out Sir Francis Drake Boulevard to Lagunitas. Just before you get to Samuel Taylor Park you cross Shafter bridge, then take a right to the pedestrian bridge. The path to the pools is right beneath it.
