Secret Bay

Secret Bay is Anilao's muck-diving classroom and one of its most productive sites at any hour. The featureless-looking sand slope resolves, subject by subject, into seahorses gripping seagrass blades, flying gurnards fanning electric-blue wings, snake eels periscoping from the bottom, and octopus, from coconut to the occasional blue-ringed, working the litter of shells and human debris. Night dives raise the strangeness: bobbit worms, stargazers buried to the eyeballs, and squid hunting under torchlight. Guides move slowly and low; the site rewards patience over coverage, and a 60-minute dive can pass in a 30-meter radius.
