Nature & Outdoors
Hon Mun island holds the best-preserved reef in Nha Trang Bay, with visibility that typically ranges from five to ten meters depending on season. Boats from the mainland take about forty minutes and most operators include snorkeling gear in the price.
Keep a horizontal distance from coral at all times and avoid standing on the reef, even where it looks like bare rock, since new coral growth is often invisible until you are close. Reef-safe sunscreen applied well before boarding keeps the chemical footprint down for everyone diving that day.
