- Cape Breton's Cabot Trail (Nova Scotia): This 300km (185-mile) loop through the uplands of Cape Breton Highlands National Park is one of the world's great excursions. You'll see Acadian fishing ports, pristine valleys, and some of the most picturesque coastline anywhere.
Cobequid Bay (Nova Scotia): When it comes to scenery, Cobequid Bay (near Truro) is one of the region's better-kept secrets. The bay is flanked by two roads: Route 2 runs from Parrsboro to Truro; Route 215 from South Maitland to Brooklyn. Take the time to savor the rocky cliffs, muddy flats, and rust-colored bays.
Fundy Trail Parkway (New Brunswick): East of Saint John, you'll find this parkway winding along the contours of the coast. Get out and stretch your legs at any of the two dozen lookouts along the way for fantastic cliffside views. Or if the tides are out, clamber down to one of the stretches of sand nestled between the rocks.
Prince Edward Island National Park: Much of the north-central shore of PEI is part of a national park. The quiet park road tracks along the henna-tinted cliffs and grass-covered dunes. The coastal road is interrupted by inlets in spots, but each segment is still worth a leisurely drive, with frequent stops to explore the beaches and walkways.
