Shoreline: USGS National Hydrography Dataset (NHD Waterbody, Permanent ID 129731719), public domain. State outline: U.S. Census Bureau TIGERweb. Points: MassWildlife Office of Fishing & Boating Access sites (MassGIS). Dashed trails: © OpenStreetMap contributors (ODbL). Interactive map: Leaflet with © OpenStreetMap contributors. Not for navigation.
OpenStreetMap shows about 1.7 mi of public hiking and walking trail within about 100 m (330 ft) of the Chauncy Lake shoreline, mostly along the north, south and west shores. They follow about 70% of the shore, so you can walk most of the way around but not a full loop.
No trailhead is mapped for these trails. The closest public access site is Lake Chauncy, right on a shoreline trail (MassWildlife OFBA access data).
The dashed brown line on the lake map shows these trails. We include paths, footways and marked trails that OpenStreetMap doesn't mark as private, and leave out roads, sidewalks and snowmobile corridors. Mapped trails can still cross private land or close for the season, and not every trail is mapped, so follow posted signs.
Trails: © OpenStreetMap contributors, available under the Open Database License (ODbL). Map data as of Oct 9, 2026. Trail lengths count only the parts within about 100 m of the USGS NHD lake outline.
We found 4 campgrounds and RV parks within 15 miles of Chauncy Lake. Distances are straight-line from the nearest point on the shoreline, so driving distance is longer.

Green tent icons on the lake map mark campgrounds near the shore, and the interactive map shows the closest 12. Amenities are listed only where a source records them; call or check the campground's website before you go, since seasons and rates change every year.

Live from the National Weather Service API for the lake's coordinates (42.2940, -71.6119). The nearest station may be several miles away. NWS forecast for Chauncy Lake. No live water-temperature sensor is shown because we haven't found a public one for this lake.
Based on solunar theory, an estimate. Major periods (about 2 hours) center on when the moon is directly overhead or underfoot; minor periods (about 1 hour) center on moonrise and moonset. The 0–100 activity score rises during those periods and gets a boost near sunrise and sunset and around the new and full moon. Weather, water temperature and pressure often matter more. Sun and moon times are calculated in your browser from the lake's coordinates with standard astronomy formulas, shown in ET (America/New_York), and accurate to within a few minutes.

Beaches: © OpenStreetMap contributors (ODbL), within about 150 m (500 ft) of the lake outline. A mapped beach is not a guarantee that swimming is allowed, supervised or safe; some town beaches need a resident sticker even when the map doesn't say so. Check posted rules and water-quality advisories before you swim.
