Tuna Alley - Donsol & Sorsogon
Tuna Alley, as the name suggests, has a reputation for pelagics, though we found it’s less about guaranteed encounters and more about the *potential*. At 23 metres, it’s a comfortable intermediate dive, mostly a drift along a sloping wall. We’ve spotted large schools of jacks here, often cruising in the blue, and on a good day, the occasional dogtooth tuna makes an appearance. It’s a site for those who enjoy letting the current carry them, keeping an eye out for bigger fish rather than focusing on macro life.
