Siquijor is a reef-heavy destination with a strong muck diving character running through many of its sites. Sub-areas spread around the island, with Lazi holding the largest concentration of sites, followed by Tubod, Paliton, Salagdoong, and Sandugan. The site mix spans coral reefs, walls, drop-offs, muck slopes, seagrass beds, and artificial structures. Most sites suit beginner divers, making the island unusually accessible. Signature species include the Ornate Ghostpipefish, Chromodoris Nudibranch, and Sea Krait, observed reliably across the reef.

Shallow entry points at reef and muck sites give newer divers plenty of comfortable options. A smaller number of sites, such as Balayang Kugtong, are rated intermediate, providing progression for those building experience.
Lazi has the largest concentration of sites and includes the muck and artificial reef character of Lazi Bay Pier alongside reef sanctuaries. Tubod features a mix of reef, wall, and artificial reef structures. Paliton and Salagdoong offer reef diving with both shore and boat access at several sites. Sandugan rounds out the island's coverage with its own cluster of reef sites.

Several other sites, including Sawang Reef, Gabayan Reef, and Campalans Wall, are boat-access only. Operators including Vibrations Dive Center, Reef Turtle Dive Center, and Mystic Diving Services are based in the region to facilitate boat trips.
