Key Dive Site Facts
Dive Site Overview
Diving Had Nuan (Koh Lan Vak) offers a shallow reef exploration within the Pattaya area, frequently approached as a drift dive because of prevalent currents. An average depth of 9 m (30 ft) makes it especially accessible for recreational divers.
Reef formations characterize the site, offering a different underwater experience from deeper wreck or wall dives. Some divers report limited marine life, yet others consider it a site "good enough to explore one time," suggesting variability in conditions and sightings. Its proximity to dive centers in Pattaya makes Had Nuan a convenient option for local excursions.
Drift conditions, typically around 2 knots (3.7 km/h), ensure a dynamic underwater tour rather than a static exploration. Divers might encounter various reef inhabitants, with occasional reports of larger pelagic species like turtles, sharks, whales, and dolphins; however, these are not consistently guaranteed. Adjust expectations for a relatively shallow, current-influenced reef exploration.
