The St John River winds along the western border of the province past forests and lush farmland. It drifts through Fredericton between tree-lined banks and around flat islands between rolling hills before emptying into the Bay of Fundy 700km later. The river is the province's dominant feature and for centuries has been its major thoroughfare. The valley's eye-pleasing landscape makes for scenic touring by car, or by bicycle on the Trans Canada Trail (TCT), which follows the river for most of its length.
Two automobile routes carve through the valley: the quicker Trans-Canada Hwy (Hwy 2), mostly on the western side of the river, and the more scenic old Hwy 105 on the eastern side, which meanders through many villages. Branching off from the valley are Hwy 17 (at St-Léonard) and Rte 385 (at Perth-Andover), which cut northeast through the Appalachian highlands and lead to rugged Mt Carleton Provincial Park.
