The beach is for Westborough & Northborough residents only & during the summer season there are lifeguards on duty. It’s clean & kid friendly with a decent playground area & a covered picnic table area. There is a walking/hiking trail on the backside of the lake that is dog friendly(most are off-leash). .. unfortunately many people with large dogs don’t pick up their dog’s s#!t, so watch your step. Boats are allowed & people occasionally wake-board or waterski on the lake, but jet skis are prohibited.
