You’ll want to visit Dungeon Provincial Park the same day you go to see the Cape Bonavista Lighthouse. You’ll see the sign for the park on your right when you are driving out to the lighthouse. We went to see the lighthouse first and stopped at The Dungeons on the way back.
You follow a gravel road for a couple of kilometers, all within site of the lighthouse. There is an excellent viewing area to see this amazing pair of sea arches. You can also follow trails to the other side of The Dungeons. There are places that are a little treacherous and you have to be careful.
When you leave The Dungeons, continue on the same gravel road towards the town of Bonavista. When you get back to a paved road, you can turn left and check out the community of Spillar’s Cove.
