World Bog Snorkeling Championship
You've perhaps tried snorkeling while on vacation near a coral reef. This is not that. The World Bog Snorkelling Championship, held at the dense Waen Rhydd peat bog near Llanwrtyd Wells in Wales, involves competitors racing through a filled trench cut through a peat bog. Snorkel gear is used, but don't expect any great underwater views in this murky water.
