Sandy Beach — Guernsey State Park

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.

Guernsey State Park, Sandy Beach

Decent park, sites are fairly spread out. Dogs not allowed on the beach areas and lots of rangers. Hot with very little share if in an electric site. Sites by the water don't have electric, but have shade. Zero cell phone service in campground, but pull 1/4 mile out and great service. Nice right on the water. Clean lake. Stayed in Sandy Beach campground at Guernsey State park.

Awesome place to visit

A wonderful place to tent camp. Very quiet area, and sites are usually secluded. Gorgeous views. The reservoir is not good for fishing, so we went to the nearby grayrocks reservoir and had luck there. Also, the water is freezing! We tried swimming. There was also a small wildfire while we were there.

Could be a whole lot better

From the grumpy lady at the gate to the trashed campsite this could have been a bad experience but I didn’t let that get to me. Cleaned it all up and set my sites on a great weekend. Then the train came... and another one... all night long. At least there was water this time. All of the camper sites were supposed to be full so I decided to use a tent only option. So many open sites when I got there and they never filled. IDK maybe it’s a Covid thing. Not really a campsite I was to use again. I was at Sandy (should be called thorny) beach.

Go for the scenery, not the facilities

We stayed four weeknights and had a pretty good time. The sites were loose gravel and very unlevel. Not too crowded during the week. The vault toilet was close to our site but you had to really need to use it to go in there. (Think ‘fly-tornado’ when you open the door.) We ventured out to use the shower house and found that it was a single shower for both men and women, for the entire state park! We couldn’t believe it... but more surprising was that it was a pay-to-use shower... $1 for the first four minutes and a quarter for each additional minute thereafter. Not a huge cost, granted, but we paid around $40/night for a campsite. That’s double what we’re used to paying for a much nicer campsite in our part of the world. The views around the lake were awesome. We’ll go back just for this reason. There were many trails in the park but most were poorly marked and some were simply not able to be found due to overgrowth.

Great base camp

We stayed here and traveled to the local sites. The camping area has a great view. The RV sites are pretty level and some have power and water. At the entrance is a good place to fill up fresh water tanks if you are staying at a dispersed site. The dump station is at the entrance as well. The staff and Park Rangers were very kind and courteous as we visited the different historic locations. We will definitely return.

Massive Campground with Plenty to Choose from

If you can't find a campground you need to not be camping. There are options ranging from Tent to Yurts. It really is a diverse place. Lots of big rigs with big boats at this place. The sites range from no electricity (which made it a bit louder with generators going at night) to 50 amp. Little dusty in places. We stayed in Sandy Beach and had a great view of the water which was perfect at sunset, but we also had the trains near as well. The campground didn't have flush toilets which is why most have their big rigs to use. The town itself doesn't offer too much and it looked as though most people were there to boat.

Boats and RVs

This camp site is not ideal for those who want a camp site away from it all. There are a ton of RVs that are setting up at all hours of the day and night. My camp site was near a very active railroad track. The bathroom facilities were clean and we were by the resevoir. Overall, just not what I was looking for. The site was super pricey once all the fees were included. Not worth it.
