Hike one of the many trails in Acadia National park including The Jordan Pond Path. Or visit Jordan Pond House Restaurant for some drinks and the views! The Standard Entrance Pass to the park is $35 per vehicle. You can buy passes in advance on Recreation.gov, or purchase them in person at the park. You need a reservation to visit Cadillac Summit Road which is $6 per vehicle (in addition to your standard entrance pass). These are ONLY sold in advance through Recreation.gov. They are not sold at the park entrance.
Enjoy shopping, local food, and many breweries. This is the hot spot of Bar Harbor!
