Twin Rocks Marine Sanctuary - Anilao
Twin Rocks is a popular Anilao site, known for its two large rock formations rising from the sandy bottom. Expect to see the usual suspects here, like scorpionfish tucked into crevices and colorful nudibranchs crawling on the rocks. It’s a good spot for newer divers, with generally mild currents and an easy profile, perfect for longer bottom times and practicing buoyancy. We find it’s also a solid choice for macro photographers.
