"Anilao" is shorthand for a stretch of coast in Mabini, Batangas that actually spans several barangays — and the freediving scene clusters in a few of them rather than spreading evenly. If you're deciding where to base yourself, the barangay matters, because it determines how close you are to your school, the boat, and the sites you'll dive.
Bagalangit
Bagalangit is one of the barangays along the dive coast, with its own cluster of operators and access to nearby sites. To see exactly which freediving operators and spots are based there right now, check the live freediving in Bagalangit page — it lists the verified hosts and recommended sites for the area.
Anilao Proper
Anilao Proper is the barangay most people picture when they hear the name, and it has its own set of operators and entry points. The current operators and spots are on the freediving in Anilao Proper page.
Which should you choose?
For freediving, the deciding factor isn't really the barangay — it's the school and instructor you want to train with, and then basing yourself nearby. Pick the host first, note which barangay they operate in, and stay close. Compare the hosts side by side by browsing freediving schools across Anilao, and once you've chosen, read Where to Stay in Anilao for Freedivers.
