Land for Sale in Seneca, SC

Seneca sits in Oconee County with three lakes around it — Hartwell, Keowee and Jocassee — and the mountains rising behind them. Land here is largely a question of which water a parcel is near, and under whose rules.

  • Lake Keowee parcels, where Duke Energy governs the shoreline and dock permitting
  • Lake Hartwell parcels, where the Corps of Engineers does
  • Wooded mountain tracts north toward Walhalla, Salem and the Jocassee Gorges
  • Farm and pasture ground south and west, and homesites in town on public utilities

US-123 runs through Seneca toward Clemson and Easley, SC-130 climbs north toward Jocassee, and Oconee remains one of the least developed corners of the Upstate. Lake Keowee homes show what has already been built on the water.
