The Inkwells are small, deep, dark pools beside Sir Francis Drake Boulevard in Lagunitas, West Marin. They aren't marked, but they're easy to find. When driving along Drake Boulevard, the Inkwells are just beyond where the houses stop and Samuel P. Taylor State Park begins. As you cross a bridge called Shafter Bridge, the Inkwells are directly on your right, underneath a reddish-colored bridge called the Inkwells Bridge. You walk down a crumbly path to the right of Inkwells Bridge to get to the beautiful, swimmable pools along Lagunitas Creek. There are two of them, one bigger than the other. There are rocks to jump off of and sun to bask in. It is the perfect place for a summer afternoon!
