Mountain biking at Acadia (Maine): John D. Rockefeller, Jr., built the carriage roads of Mount Desert Island so that the gentry could enjoy rambles in the woods with their horses -- away from pesky cars. Today, this extensive network offers some of the most enjoyable, aesthetically pleasing mountain biking anywhere.
Kayaking the Maine coast: With its massive and serpentine coastline and thousands of islands, most uninhabited, Maine is a world-class destination for those who like to snoop around by kayak. The Stonington area is considered the best spot for kayaking in Maine, but it's hard to go wrong anywhere north and east of Portland. Beware of dangers in the form of tides and weather -- kayak with a guide if you're a novice.
Canoeing the North Woods (Maine): Maine has thousands of miles of flowing rivers and streams, and hundreds of miles of shoreline along remote ponds and lakes. Bring your tent, sleeping bag, and cooking gear, and come prepared to spend a night under the stars listening to the sounds of the loons.
