Water temperatures normally range between 25°C and 30°C, peaking from June to August and cooling slightly early in the year, always pleasant for diving in Nha Trang or a relaxing snorkeling session.

Marine biodiversity in Nha Trang: An underwater treasure trove

The waters of Nha Trang guard one of the richest marine ecosystems in the country. The bay is home to over 350 species of reef-building hard corals, along with soft corals, gorgonians, and colorful sea fans that create spectacular underwater scenery.

Moving among the reefs are hundreds of tropical fish species: from butterflyfish and clownfish to groupers and schools of barracuda. There is no shortage of surprising small organisms like nudibranchs, true “living jewelry” for divers who love macro photography.

Beyond the reefs, the ecosystem includes seagrass beds that offer shelter to juvenile fish and help keep the waters clear, as well as sandy zones where you might encounter rays, starfish, and seahorses.

Famous diving spots in Nha Trang

Hon Tam: Relaxation and adventure minutes from Nha Trang

If you are looking for a complete day experience blending sea, sports, and wellness, Hon Tam Island is the perfect choice. Located just 7 km southeast of Nha Trang, this island is easily reached by speedboat in about 15–20 minutes. Despite its proximity to the city center, the atmosphere is completely different: white sand, crystal-clear waters, and a slow pace of life.

For action lovers, the island offers a wide range of water sports: jet skis, kayaking, flyboarding, and parasailing. Its shallow and safe waters also allow for snorkeling near the shore. Hon Tam is famous for its exclusive resorts, such as the MerPerle Hon Tam Resort, and its popular mineral mud baths, a wellness experience with an ocean view.

Whale Island: A hidden gem for nature lovers in Nha Trang

One of the most unique and wild places for diving in Nha Trang is Whale Island (Hon Ong), located about 100 km north of the city. The island feels completely isolated from the urban world: a setting immersed in nature, with wooden bungalows hidden among palm trees and a slow rhythm far from traffic.

Whale Island is a true paradise for diving enthusiasts; the waters around the island maintain an intact and rich ecosystem. You can snorkel to observe colorful corals at the surface or go deep with tanks among untouched reefs, groupers, and clownfish.

Hon Mun Nha Trang: The heart of the coral reef

Hon Mun Island was Vietnam’s first Marine Protected Area. Walking along its beaches or diving just below the surface feels like entering a natural aquarium.

However, due to environmental degradation, scuba diving and snorkeling activities at Hon Mun were suspended starting in 2022 to allow the fragile ecosystem to regenerate. While you may not be able to dive with tanks here currently, the commitment to letting nature heal highlights the importance of sustainable tourism in the region. Visitors can still enjoy boat tours to admire the scenery responsibly.

• Choose certified operators: Opt for centers that follow eco-friendly practices.
• Use reef-safe sunscreen: Protect your skin without harming the corals.
• Look, don’t touch: Avoid touching corals or collecting shells.
• Reduce plastic: Minimize waste and respect protected area rules.
