Do they have A.C.????

If you rent a cabin you'll have AC. Otherwise it's caming on your own with tent's. Campsites go have a grill but you'll need to bring charcoal. They also have showers and bathrooms. My advice with just camping there 2 weeks ago, it was super hot. Try planning a trip there a little later in the year when it's a little cooler

Is a natural camp, so no a.c., No electricity on the tent site, you have to bring your own lantern.

Can you be more specific on your question, there is no a/c only on the office
