Prerequisites/Experience Required

Among the sites we visit, divers of almost any certification level can join. However, Richelieu Rock is deep and exposed – so we require that all divers have recent diving experience (within the last 12 months) before joining this trip. Not only will it make the trip far more enjoyable and safe – but it also allows you to make the most of these these trips!

Did you know you can easily do an Advanced Course while on the trip? The cost is incredible and the opportunity priceless!

Finally a note about insurance. As always, Wicked Diving and our staff make every effort to assure your safety but there is no way that we can prevent accidents and acts of God.

We recommend Nomads as a very good company designed for these kind of expeditions.
