This interconnected system of walking and biking trails (which is fully wheelchair-accessible) follows the inner harbor and is used year-round by residents and visitors alike. It's a great spot to observe the working port from the north side of the city to downtown; it's currently 2 mi/3 km long. The interpretive panels along the way explain the city's rich history. Along the waterfront, Saint John. Phone 506-674-4278. http://www.sjwaterfront.com.
