The town's general park rule applies (parks close at sundown).
Season
Swimming area staffed and roped off seasonally, roughly Memorial Day through August; the town has had to vote annually on funding lifeguards, so the swim season is not guaranteed year to year.
From Memorial DayAccessibility
No accessible beach features documented at the swim area itself; the adjoining Conservation Forest loop trail across the road is built to accessible standards (gentle slopes, crushed-stone surface).
Lifeguard
Lifeguards staffed in summer via a contract with Berkshire South Regional Community Center; funding is voted separately each year and was in doubt for the 2026 season pending a June 29, 2026 special Town Meeting.

Dogs are prohibited in the beach and picnic area (posted town rule, enforced by fine: $10 first offense, $20 second, $50 third). Dogs are welcome, leashed, at the boat launch area across the road.
