CharacterPinnacle dive

StandoutRich in charismatic marine life

Seal Rock is a robust pinnacle rising from the chilly Nova Scotia depths. We’ve found it’s a site best suited for hardy temperate water divers, especially those keen on macro life. Keep an eye out for nudibranchs tucked into the crevices and various anemones clinging to the rock face. The conditions can be challenging, so good cold-water experience is a definite plus.

Safety Notes

Cold water this month (avg 15°C). Drysuit or thick wetsuit (7mm+) recommended.
