Walk this square, which is a 1.4 mile loop. Interesting architecture and three river crossings make this one lively and interesting.
At the intersection of East Main Street and Pearl Street, proceed east on Main Street, with the octagonal railroad towers at your back. Reach Willow Street, and turn right, toward the Salmon River, which is crossed midway.
Turn right on College Avenue, and after this river crossing, turn right on Pearl Street, cross the river again, and complete the loop.
