On this survey map, look to the left of the "O" in "Forest Beach Rd"...see the 4 dots and road in the red ellipse? That's the cottages and driveway! (Map only shows 4 of the 6 units)
....and it's only about a 5 minute walk (or a ONE minute or less drive!) from cottages to a choice of two beaches (Pleasant St @ 1/4 mile or Forest Beach Rd @ 1/3 mile) on Nantucket Sound! Both beaches have small (15 and 35 vehicles, respectively) parking lots and they're FREE!
