Located at Cape Bonavista, on Newfoundland's east coast is Dungeon Provincial Park, a short but scenic route that winds along the rugged Newfoundland coastline. You can drive through this very small park, but for the more adventurous people there is a small sheep trail that runs from the road through 2km of the scenic coast.

The trail runs through a large sheep pasture (watch your step) to the sheer cliffs that line the shore of Bonavista Bay. The rugged shoreline features many sea stacks and caves and a great view of the lighthouse at Cape Bonavista, a provincial historic site.

The dungeon itself was once two sea caves that were side by side, but over time the pounding sea eroded the rock so much that the top caved in creating a large sinkhole. The result is a very neat looking sinkhole that has two large sea arches connecting it to the ocean. Looking at it from above it sort of looks like a giant skull.
