You’ll exhaust yourself long before you exhaust the possibilities for active fun here. What to do first? If hiking’s your thing, head into Camden Hills State Park or one of the many nature preserves scattered throughout the region. There are many miles of trails to choose from and even some cliffs for those into the heart- pounding pursuit of rock climbing. Biking — both off- and on-road — is excellent too. There are several golf courses (both 9 and 18 hole), as well as fitness facilities. And there are plenty of opportunities to head out fishing, either with a guide service or on your own. More leisurely activities include “workplace” tours, where you can see cool products being made or grown. Come winter, the same network of trails loved by hikers is enjoyed by Nordic skiers and snowshoers. Alpine skiers, meanwhile, soak up a breathtaking ocean view as they whiz downhill at Camden Snow Bowl — an experience you can’t find anywhere else on the East Coast.
