Hiring a bike in nearby Bar Harbor is a breeze, and a good way to avoid traffic snarls and parking problems. All Island Explorer buses accommodate bikes (from four to six per bus), though if you want speedy transport to the carriage roads, take the free Bicycle Express. This takes cyclists and their wheels from Bar Harbor's Village Green to Eagle Lake.
The free shuttle system, the Island Explorer, features 10 routes that link hotels, inns and campgrounds to destinations within Acadia National Park. Route maps are available at local establishments and online. Most of the routes converge on the Village Green in Bar Harbor. The shuttle runs from late June to mid-October.
