Peirce Island

Portsmouth

Peirce Island along the Piscataqua River is a very popular advanced dive site. Divers can explore the fields of hydroids and anemones, the entire site teaming with life. A popular spot for macro photographers who seek out the alluring colors of the nudibranchs during the winter months. There is also a beautiful sloping wall, Luis' ledge that is one of our favorite places in all of New England. It’s a dive that’s not recommended during summer months given heavy boat traffic that’s coupled with very strong river currents. Extremely tidal. Beware and know you tide math before attempting this site as there is HEAVY boat traffic with large vessels and dangerous currents.
