Boating - GUERNSEY


One of the primary attractions at Guernsey State Park is the boating and water recreation opportunities. Boating enthusiasts may enjoy the 2,400 acres of Guernsey Reservoir.


  • Boating is allowed on the entire reservoir as water levels allow.
  • Boat access points are found on the west side of the reservoir at the Sandy Beach launch area, the southeast end of the lake at the the main boat launch area and at the north end of the reservoir at the Long Canyon ramp area.

Boating is permitted as water elevation levels allow access to the reservoir.


To access the reservoir to enjoy the water all vehicles are required to have a SPHS&T daily use permit.
