Read the swimming notice before choosing this lake
The state-linked day-pass notice says there is no designated swimming area and recommends another park for swimming. This guide replaces older island-entry advice rather than presenting it as a current route.
Use photos as context, not instructions
The gallery's Rock Point sign is not a Rock Island direction. Historical photos do not identify a monitored swimming entrance. Check the park's current rules before choosing any activity.
Pay on arrival, not to reserve space
Advance payment does not guarantee entry. If the booth is closed, applicable parking fees still require online payment on the visit date. Have a backup plan rather than using roadside parking.
Additional scenery reviewed October 20, 2026
Additional photographs from the saved Mashapaug Lake collection show a sunlit wooded shore and a wooden footbridge on a woodland path. They add landscape and walking context, not directions to Rock Island or a designated swimming entrance. The bridge location, present condition and onward route have not been independently surveyed. These photos do not change the state-linked swimming notice discussed above or establish present water quality.
Getting There
Use Bigelow Hollow State Park, 298 Bigelow Hollow Road, Union, CT 06076. Confirm the intended lake on the park map. The retained historical pin is unverified, not a lake entrance. Do not follow the old Rock Island water-entry directions.
Quick Navigation
Access Notes
Park hours: 8 a.m. to sunset. Once parking reaches capacity, no additional vehicles enter that day. Do not park outside on Route 171.
Plan Your Visit
Parking & Access
Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.

Obey No Swimming and No Entry signs; keep off islands and rocks. Qualified scuba access is not general swimming approval. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.
Seasonality & Flow
Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.

Joshua Havens created Hidden Swimming Holes to make it easier for people to find — and safely visit — natural freshwater swimming destinations across the United States. He researches access conditions, water quality resources, and land management rules so you don't have to start from scratch. He holds a strong belief that good outdoor recreation information should be accurate, honest about its limitations, and freely available.
