Margaret Lindley Park is operated by Williamstown's Conservation Commission and the town. Its park page identifies a pond with an artificial beach fed by Hemlock Brook. Swimming runs Memorial Day through Labor Day, dawn to dusk. October is outside the published swim season; year-round hiking is a separate activity.
The town tests water weekly and publishes notices on the park page and official social channels. A June 29, 2026 reopening follows the June 24 bacteria closure. Neither notice proves conditions on a later visit. A summer Park Ranger works Tuesday through Saturday, but the page does not confirm lifeguard coverage.
During swim season, dogs are prohibited throughout the park, not just at the beach. The specific park page welcomes them from Labor Day through Memorial Day. Follow current signs and town requirements, and keep out of the roped-off recovering grass mentioned in the tree-removal notice.
The town lists a picnic lawn, tables and grills, plus woodland trails alongside Hemlock Brook toward Harmon Pond. Use the linked trail map for your route. Those hiking destinations are not established swimming areas. Confirm current toilets, water availability and mobility requirements rather than relying on historical gallery photos.
Use the current town park page and its linked trail map for Margaret Lindley Park in Williamstown, Massachusetts. Follow signed public parking and pond access. The retained historical coordinate is not a verified beach entrance. Town hall contact addresses are not the park's entrance.
Swimming operates Memorial Day through Labor Day, dawn to dusk; hiking is available year-round. The June 29, 2026 reopening notice supersedes the June 24 bacteria closure, but is not an October swimming-opening notice. Stay out of the roped-off grass area identified after June tree removal and follow any newer signs.
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.
Current swimming permission has not been independently confirmed for this listing. Check official rules, fees, hours, and closures before visiting. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.
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.
Bring sturdy water shoes to protect your feet on rocks and slippery surfaces. A waterproof dry bag keeps your phone, keys, and valuables safe. Pack a quick-dry towel, sun protection, and drinking water - never drink from the natural water source.
Nearby places from saved public map data, not necessarily facilities at the swimming spot. Confirm access, hours, fees, and amenities with the operator before you drive.
