Marble Arch
About Marble Arch
Marble Arch sits in an area known as “Whale shark alley” and is named for its dramatic swim-through topography. It is described as well-suited to open water divers who want to practice buoyancy while exploring the site’s formations. Along the sandy margins, divers can find rays and guitarfish, with abundant nudibranchs and other small critters for macro-focused diving.
