However, if you want to dive shipwrecks, the area is pretty much a wilderness. There is but one dive shop out here, and you are a long way from any hospital. Lake Calabogie has the only dive shop in the region and has a full hotel facility to accomodate guests. Many of the lakes and rivers are controlled by Ontario Hydro. Beneath the waters of Black Donald lake, lies the former town of Black Donald.
Divers can visit the empty streets and foundations of former homes.
There is a single shipwreck in the interior region, near Barry's Bay. Rivers such as the Madawaska are popular spots with white water enthusiasts, and therefore only suitable for the experienced current divers. Mazinaw Lake on highway 41 is part of Bon Echo park. A towering cliff rises from the lake challenging climbers. The cliffs continue unseen deep into the depths.
