We've been to Halifax several times before, so we just strolled along the Harbor Walk to the Maritime Museum and went there. It was a nice museum with some things from the Titanic.Our friends took a van tour to Peggy's Cove and for lobster and had a great time.
We rented a couple vans from Enterprise and drove to St. Martin's and the Fundy Trail. It was easy to do and the views were beautiful. Tides were wrong for visiting the sea caves in St Martin's.
Again, another place we've been. We took the free LL Bean bus around Arcadia and strolled through the town.
We rented cars and drove to Rockport along the coast. Lobster lunch :). Drive back to Boston was the main adventure. What a city to drive in. Not fun.
Included a drive along Ocean Drive. Mansion had the nicest audio tour setup I've seen anywhere as far as ease of operation.
