South Branch Grass River.

The South Branch Grass River drains north from the Cranberry Lake Wild Forest toward the main stem of the Grass River, threading through a mix of state forest land and private holdings west of Tupper Lake village. The corridor is part of the larger Grass River watershed — a low-gradient maze of rivers, oxbows, and wetlands that sees more canoe traffic than foot traffic, more beaver sign than blazes. Access is scattered and seasonal: some stretches are best reached by paddling upstream from public put-ins on the main river; others dead-end at private land or logging roads that may or may not be passable depending on spring runoff and timber operations. If you're looking for solitude and don't mind navigating by topo map and deadfall, this is functional wilderness — just verify access before you commit to a long carry.
