Madonna Rock is one of the iconic dive sites in Nha Trang, located near Hon Mun Island, in an area renowned for its coral reefs and biodiversity. The spot is known for its rock formations, small underwater passages, and swim-throughs, particularly in shallow to moderately deep areas. Divers discover a more interesting relief than just a flat reef, with arches, rocky blocks, and walls covered with soft and hard corals. Marine life can include clownfish, angelfish, butterflyfish, parrotfish, schools of banded barracudas, lionfish, mantis shrimp, nudibranchs, moray eels, and scorpionfish.
