Seven miles [11.3 kilometers] past the state park entrance, watch for the turnoff to Pembroke Falls, one of the nation’s largest reversing falls, a tidal phenomenon. The road to the falls is poorly marked: Turn right off U.S. 1 onto Leighton Point Road; after 3.2 miles [5.2 kilometers], turn right and continue for 1.2 miles [1.9 kilometers] past the Clarkside Cemetery. When the road forks, go left and continue 1.7 miles [2.7 kilometers] into the park. The tip of Mahar Point provides a fine view of the fierce whitewater created when Dennys Bay and Whiting Bay flow into Cobscook Bay. Watch for bald eagles, ospreys, and seals.
Halfway between the Equator and the North Pole lies the town of Perry, named for Commodore Oliver H. Perry, a hero of the War of 1812. Two miles [3.2 kilometers] from the Perry town line, at the junction of U.S. 1 and Rte. 190, turn right onto 190 for Eastport. For the first few miles the road passes by the Pleasant Point Indian Reservation, home to over 700 Passamaquoddy Indians. The
Sipayik Museum (+1 207 853 4001) on the left tells the tribe’s story. It’s another 5 miles [8 kilometers] to downtown Eastport. To see Old Sow Whirlpool, one of the world’s largest, turn left onto Water Street at the end of Rte. 190, pass the entrance to the Deer Isle ferry, and continue to Dog Island at the end of the road. The whirlpool is best seen
about two hours before high tide.
Back at the junction of U.S. 1 and Rte. 190, continue north on U.S. 1 for 2 miles [3.2 kilometers] to the 45th Parallel Picnic Area. The red granite stone marking the halfway point was erected in 1896 by the National Geographic Society. About 5 miles [8 kilometers] from here, pull over at the next rest area to view the red granite cliffs of the St. Croix River.
Between Robbinston and Calais look for 12 small, sequentially numbered granite markers on the river side of the road. Lumberman and journalist James S. Pike put them there in 1870 to time his racehorses. St. Croix Island National Historic Site (+1 207 288 3338), at the Calais town line, is named for two long coves that meet to form a cross. Samuel de Champlain landed
here in 1604, making this island in the middle of the St. Croix River the site of the country’s first white settlement north of St. Augustine,
Florida.
The city of Calais (CAL-lus), along the bank of the St. Croix River across from St. Stephen, New Brunswick, is one of the busiest ports of entry along the 3,000-mile [4,828-kilometer] U.S.-Canada border. Continue north on U.S. 1 through town for 5 miles [8 kilometers] to the 16,080-acre [6,507-hectare] Baring Unit of the Moosehorn Wildlife Refuge (+1 207 454 7161). With the Edmunds Unit to the south, it’s the
northernmost in a chain of migratory bird refuges that extends from Maine to Florida. A fitting sentinel at the end of this road to the border,
the American bald eagle has taken up residence here. Nesting areas line the entrance to the refuge at Charlotte Road.
