Great Blue Hole
The Great Blue Hole is a massive, remote marine "sea hole' off of the coast of Belize. It's 1,000 feet wide and nearly 400 feet deep. This is a popular spot for scuba divers due to its crystal clear waters, valuable marine life, and impressive coral reefs.
Giant's Causeway
Giant's Causeway is a natural wonder on the coast of Northern Ireland. There are nearly 40,000 polygonal columns that were created by volcanic activity. They are made of black basalt and have a pavement-like texture. Local lore says that a giant named Finn McCool threw the chunks of the coast into the sea so that a stepping stone path to Scotland would form.
