my friend and i fly into boston for a 9 day vacation june 27 - july 5. we are renting a car. is it feasible to drive up the coast to bar harbor/acadia and then back to boston through NH/ vermont? we want to end our trip in boston july 3-5 and do the boston stuff at the end of our trip. we are looking for outdoorsy adventures - hiking, biking, swimming, etc. also are the whale watching excursions good?
