This review is for the campground on Big Island, we stayed in spot 21.
The spots are very well maintained, but close to neighbors. The facilities are brand new, and very clean. Had a toilet, shower, and dish washing area. The park office does sell firewood and other things, so definitely take a look when you check in!
We dropped our kayak into the lake at the boat launch, which was a 2 minute drive to the other side of the island from the campsite. The lake was great, and calm.
We really enjoyed it here! Except for the mosquitoes, so pack repellent!
