Shoreline: USGS National Hydrography Dataset (NHD Waterbody, Permanent ID 34973749), public domain. State outline: U.S. Census Bureau TIGERweb. Points: Georgia DNR WRD water access points and OpenStreetMap boat ramps (ODbL). Dashed trails: © OpenStreetMap contributors (ODbL). Interactive map: Leaflet with © OpenStreetMap contributors. Not for navigation.
OpenStreetMap shows about 0.8 mi of public hiking and walking trail within about 90 m (300 ft) of the Martin Lake shoreline, mostly along the south shore. They follow about 60% 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 Boat ramp, 450 ft from a shoreline trail (Georgia DNR water 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 90 m of the USGS NHD lake outline.
Live from the National Weather Service API for the lake's coordinates (34.0052, -84.3171). The nearest station may be several miles away. NWS forecast for Martin 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.
