Within Guernsey Reservoir State Park, Sandy Beach provides drive-in and hike-in camping along the shoreline of Guernsey Reservoir. This state park campground accommodates RVs up to 55 feet with electric and water hookups available at $10 per night. Sites sit on loose gravel surfaces that campers describe as unlevel, requiring careful positioning for RVs.
The campground splits between two distinct areas. Sites near the water lack electrical hookups but offer natural shade from mature trees. Electric sites sit in more exposed locations with minimal shade coverage during hot summer days. Train tracks run close to the camping area, with freight trains passing throughout the night. Chris D. notes "Zero cell phone service in campground, but pull 1/4 mile out and great service."
Vault toilets serve the campground, though reviews consistently mention cleanliness issues. A single shower house operates on a pay-per-use system at $1 for four minutes. The reservoir water remains cold even during summer months, limiting swimming comfort. Dogs are prohibited on beach areas, with rangers actively enforcing this rule. Other camping options include Cottonwood Cove — Guernsey State Park and Sandy Point — Guernsey State Park, both within the same park system.
Sandy Beach works best for campers prioritizing water access and hookup availability over quiet conditions or premium facilities.
