Does park have camp ground?

Campgrounds in the sense of pulling a trailer hookups etc.. no. No dump stations either. You may get away with a small teardrop or pop up, but anything bigger may not be able to traverse the narrow dirt road. Stick with a tent or rent a lean-to. There is limited water available also.

Note that there are size restrictions on RVs and that no pets are allowed in the park.

Yes. There are campgrounds that allow both campers/RVs and tents but there are also camp sites that only allow primitive camping and have tent sites only.

Yes it has several campgrounds.
