Where should we park to get the island explorer?

There are different spots all over the island. Go on line to http://www.exploreacadia.com/ for schedule and bus stops. But visitors center is easy. May have to take bus to bar harbor and catch another to jordan pond

Visitor center

Visitor's centers are definitely the easiest places.

The visitor center has lots of parking, or you can get it in the the village green.

You can park and Hulls Cove visitors center. Then you can catch the Island Explorer to Jordan Pond
