One single 30 RV outlet at each site. The outlet is a standard 30R prong type plug. Standard 30/20 amp adapter will convert to regular household U ground plug.

As of summer 2020 no they did not! Source: I stayed there and I couldn’t plug my device in hahaha I even went around to other sites and checked. :(

Each site has one 30amp RV electrical hook up, thus bring a adaptor for 50 to 30, or 30 to 20/15amp.

No. You will need a 30 amp male to 15 amp female adapter. Cost about $7. GR is a beautiful park. Have fun!

Unfortunately it’s been years since we were there and I really don’t remember but I don’t believe so. We always used the 30 amp plug from the RV to the electrical stand. Your best bet is to call them directly or check their website.

We only had 30 amp at our campsite. Maybe there’s 15 amp in the tent sites?
