So who made the Japanese Tunnel? hm,er,, the Japanese? This is the repetitive question of one of our tourmates. She’s kinda old so we were trying to be more patient. We woke up at 5 am and waited for the sunrise but it was cloudy so we didn’t get to see that. We followed the trail to the Spanish lighthouse and there where we passed through the Japanese tunnel. Obviously, its made by the Japanese. It was an easy hike so I recommend everyone to do this when they stay in Corregidor.
