Blue Lagoon in Siargao is a gentle introduction to diving. It’s a shallow lagoon site, topping out at 20 metres, making it ideal for beginners or those getting back in the water. You’ll find coral patches scattered across the sandy bottom, home to various small reef fish. We’d suggest it as a good spot for a relaxed, easy dive.
