Port Williams calls itself "The Biggest Little Port in the World" (see visitor information at http://www.portwilliams.com/visitors/our-history). The town has a rich history that includes Mi'kmaq, Acadians, and Planters. This location is on the river that flows past town, which is (very) tidal at this point.
