$2 per hour while charging, but a rebate may be negotiated if you are staying in the parks units or tent sites. Several caravan charging (16Amp) plugs are available.
Ranfurly is an Art Deco township and well worth a visit. Several cafes and places to eat are available while you charge. If you are carrying your own bikes, it is a great place to sample part of the Otago Rail Trail. The local school opens its swimming pool for visitors in the summer months.
