Redditor RTWin80weeks was hiking along the beach outside of Lagos, Portugal when he came upon this amazing rock formation. It's a hole that goes deep into the earth--farther than he could see.
Other redditors claim to have been there. Ski6666 made this video showing the other side, which empties into the ocean. -SSS- thinks that this spot is at Farol Ponta Da Peidade, an area known for its exceptional natural beauty.

That's "Farol Ponta da Piedade" (something like "Piety Point Lighthouse", not "Foral Ponda da Peidade" (which makes no sense and sounds like something about farting).
