Nha Trang Divin - Hon Mun Island, Vietnam


Nha Trang is the most famous dive location in Vietnam.  I went diving with Rainbow Divers Nha Trang, the best known dive centre and most well established of the Rainbow Divers centres.


Diving regularly take place around the island of Hon Mun which was declared a 'protected' Marine Park in 2003.  Hon Mun is located to the south of Nha Trang Bay and is characterised by cliffs, caves and numerous grottoes.


The island's excellent diving is largely due to its close proximity to warm sea-currents from the equator which are particularly favourable to the development of soft and hard corals whilst offering the ideal environment to an abundance of tropical sea creatures.




 




Hard Coral, Nha Trang - Hon Mun Island, Vietnam


Hard corals are the reef builders. The hard coral polyp, such as those in Brain Coral, secrete a limestone skeleton cup around itself and live inside it for protection. When a polyp dies, its skeleton house remains intact.  The name "hard coral" derives from the skeleton which forms around the polyp.
