I just had a couple of cancellations for our trip to Acadia National Park in Seal Harbor Maine.
To give you an idea of what the trails / carriage roads are like:
Reservations are from Thursday September 22th to Thursday September 29th. (7 nights)
(2) stalls + (1) campsite (No water or electric, but they do have flush toilets) and shared tack stall = $542.50
Let me know ASAP if anyone is interested.
