This collapsed-in sea cave is located in Bonavista, Newfoundland at the Dungeon Park. I camped and kayaked here one May long weekend and had an opportunity to paddle around the sea cave. The wind was so strong it blew me right in one end and I had to paddle like the dickens to get out the other side. I did re-enter and exit a few times more after that as it was quite beautiful.   Submitted By: Stan Mac Kenzie
