Detailed review of coral diving in Son Tra: Cost, timing, and essential tips

Son Tra Peninsula – often dubbed the "green lung" of Da Nang, located just about 10–12 km from the city center, stands out with its diverse and biologically rich marine ecosystem. This area boasts over 54 coral species and hundreds of fish species, creating an ideal environment for ocean exploration activities. Compared to well-known diving spots like Cu Lao Cham or Ly Son, coral diving in Son Tra offers the advantage of proximity and easy transportation, making it suitable for a wide range of visitors, from families and couples to groups of friends.

The experience typically begins with a high-speed speedboat ride lasting just 10–15 minutes, whisking visitors away to stunning coral reef spots. Here, you can immerse yourself in the clear blue sea, admire colorful coral reefs, and swim alongside wild fish. Thanks to its convenience, impressive beauty, and flexible scheduling, this activity is considered by many visitors as a must-try experience when visiting Da Nang.

Not every area around Son Tra Peninsula has the same coral system. Several prominent diving spots are highly rated by tourists and tour operators due to their clear water, rich coral, and easy accessibility. Below are the top-reviewed coral diving locations in Son Tra:

Hon Sup

This is considered the "golden" diving spot of Son Tra Peninsula. Located less than 1 nautical mile from the shore, this area features a highly diverse marine ecosystem with around 54 coral species and 162 fish species. Clear sea waters and colorful coral clusters make it ideal for both snorkeling and scuba diving.

Bai Nghe

Renowned for its dense coral coverage and relatively shallow waters, Bai Nghe is an excellent spot to observe corals right near the surface. Many tours combine coral diving, swimming, and underwater photography in this area.

Bai But

Bai But features crystal-clear waters year-round and a gently sloping seabed, making it very safe for beginners. This area also hosts several rare coral species, making it a popular choice for family tours or light experiential trips.

Bai Nam (Bai Nom)

Highlighting fine white sand beaches and turquoise waters, Bai Nam offers a pristine natural setting. The coral system here is quite diverse, and with fewer crowds, it is perfect for those seeking a quieter diving experience.

Bai Rang, Bai Bac, and Bai U

These areas see less mass tourism development and remain uncrowded, making them suitable for visitors seeking privacy or combining diving with camping and coastal exploration.

In most diving tours in Son Tra, Hon Sup and Bai Nghe are usually the two main stops due to their vibrant coral reefs and optimal water conditions for marine life observation.

Although considered a relatively safe activity, coral diving still requires careful preparation to ensure a smooth experience and avoid unnecessary risks. Here are some practical tips:

Before you go:

• Choose a reputable operator 
• Health check: Avoid diving if you have heart conditions, asthma, ENT issues, or severe motion sickness.
• What to bring: Form-fitting swimwear, sunscreen, waterproof bag, hat, sunglasses. Do not wear easy-to-lose jewelry.

While diving:

• Always wear a life jacket and follow the guide's instructions.
• Do not touch or step on coral (it can kill the coral and cause injury).
• Breathe steadily and stay calm. Swim gently and maintain a safe distance from schools of fish.
• Do not consume alcohol prior to diving.

After diving:

• Drink plenty of water and rest at least 24 hours before flying or trekking.
