Very quiet place to stay. Unfortunately its a long drive (1.5hrs) down the island or you have to take a ferry (30min). We didn't spend a lot of time at the campsite but when we did it was nice. We camped here in a Travel Trailer.
We're visiting friends in Clinton on Whidbey Island, and they recommended the fairgrounds. Grass sites, water and 30 amp. There is a dump station available at no add'l charge. Nothing special, but adequate for our needs. The town of Langley is 1.5 miles away. We camped here in a Motorhome.
