Light House (Hon Mot) – Nha Trang Dive Site

Site Overview

Light House on Hon Mot Island is Nha Trang's premier macro diving site, a gentle rubble and seagrass slope that supports an extraordinary diversity of rare and well-camouflaged marine species. The site is renowned among dedicated macro divers for reliable seahorse encounters, with multiple species documented among the seagrass beds and gorgonian branches at depths of 8 to 15 metres. Ghost pipefish are regularly found hovering motionless among the rubble and sea fan structures, their remarkable camouflage making them a thrilling discovery for patient observers. Octopus hunt actively across the sandy and rubble substrate, displaying their extraordinary colour-changing abilities as they stalk small crustacean prey. The site's rubble and seagrass habitat, while less visually dramatic than hard coral reefs, supports a biodiversity of small and cryptic species that rivals the best muck diving destinations in Southeast Asia. Harlequin shrimp, various nudibranch species, and ornate frogfish are among the highlights documented by underwater photographers who frequent the site. The shallow depth profile allows for extended bottom times ideal for the patient searching and careful observation that macro diving demands. Light House proves that Nha Trang's diving extends far beyond coral reefs into the fascinating world of critter hunting and macro exploration.
