Most Montrealers don’t realize that one of the most beautiful National Parks in the USA (and the only one in the Northeast) is only a (7 hour) drive away! It’s an amazing place with many hikes (long and short), a long, rugged coastline, scenic drives, wildlife, and the perfect sunsets and sunrises.
Bar Harbor, the town just outside the National Park, is also great.
It’s compact, scenic, and has tons of restaurants, especially breakfast restaurants – I have never seen such a high concentration of breakfast restaurants! And our hotel, The Central House, was only $65 a night!
