We camped here with a group from work and had a great time! Large variety of sites from no shade to full shade. The photos on the parks website are a bit misleading. There is actually MORE shaded sites that what the pictures show! Roads are gravel with natural vegetation. Our site, #001, was unlevel, but easily fixed with my leggo blocks. All sites had a table and fire ring. I would suggest the waterfront sites, but these go the fastest! Bathrooms were fair, but good shower pressure and warm water. The lake had a large amount of green algae, but was warm and calm. Lots of water sports on the lake and it can get busy! We camped here in a Travel Trailer.
Jackson Lake is a great state park for fishing and water sports. We went here for the 4th of July weekend to do some jet skiing. The site has a lot of various sites (some with electric and some "primitive"). Sewer dump is at the park entrance. There are various water faucets around the park where you can fill up your water tank before you settle into your spot. The marina is fairly well stocked with food/goods. Gas was about $.40-$.50 higher per gallon compared to the city. My Verizon Wireless card did work although signal was very low. We camped here in a Motorhome.
