Isles of Shoals Steamship Company

We are known for our breathtaking sightseeing tours of the Isles of Shoals, but once October comes we still cruise the Piscataqua River and Portsmouth Harbor.  But in addition, we head inland as the Thomas Laighton cruises under the Sarah Long Bridge and into Dover Point and the Great Bay Wilderness Area to view the beautiful foliage!
