Cobb Hill Rd sits around Alstead, NH, United States, putting this jump spot in the orbit of Alstead and the broader NH area of United States. Use the saved coordinates and current map view as a starting point, then confirm the exact approach locally because cliff-jumping access can change around parks, private land, roads, shorelines, and water-management areas.
Seasonal conditions matter here, especially after storms, drought, high flow, or unusually low water. Conditions are not static: rain, snowmelt, drought, changing water levels, current, and weekend crowding can all change what looks like the same jump from one visit to the next. Treat saved route notes as background, not as a present-day clearance to jump.
The main assumed risks include cold deep water, abrupt walls, poor exits, submerged debris, and uncertain ownership or enforcement. Access should be treated as conditional until signs, land ownership, permits, and local rules are confirmed. Before anyone climbs to a ledge, inspect the landing zone from the water, identify the exit, look for submerged rocks or debris, and be willing to walk away if the depth, footing, legality, or rescue options are uncertain.
