Acadia is one of those rare places where you can enjoy outdoor activities and still be down in time to have dinner in a fine restaurant. The park offers hiking on 100 miles of trails, mountain biking on 50 miles of carriage roads, swimming in shallow and often warm lakes and ponds, rock scrambling, whale watching, and nature cruises. There are about 3 -4 campgrounds in the area. Be advised about 4 million people visit the park annually so plan well in advance. If you still don't have enough to do you can visit Isle Au Haut and the Schoodic Peninsula also part of the park.
