One of the top diving spots in the world - exploring the four WW2 cargo ships torpedoed off Bell Island. Expect excellent visibility (30m on a bad day) and collossal intact shipwrecks festooned with cold water corals / marine growth. Yes it is cold (8 degrees maximum in Sept-Oct) and the water will be below zero even at the start of summer, but it is spectacular and the dive centre staff are the nicest I have ever met. It is a long way to go just for diving, so if you do best get used to drysuits and hone your skills first. Hire a car for your visit to explore Newfoundland as well.
