Eastern Rocks at Duck Island has cathedral ledges that drop into 40 plus feet. Really beautiful diving with lots of curious seals. It’s easy to come across seals sleeping in rocks. It’ll surprise both diver and seal. I came across several two hand lobsters sitting on the cathedral ledges. Two hand because I needed two hands across the carapace to hold them. Large amounts of fish and photo opportunities at Eastern Rocks. Contact Cyntillation Aquatics at 603-305-0437 for booking. You can also contact Diver’s Den or Portsmouth Scuba as well.
