Shark Fin Reef

Located southeast of island number 3, Shark Fin Reef gets its name from the three pointy tops of the reef, looking like a shark’s fins, which protrude from the water, when the tide is low.

Detailed Map of Shark Fin Reef - Similan Islands 1 2 3This reef boasts granite boulders as long as 1 kilometer. It has steep walls shaped so perfectly that one would think they were the result of someone’s artwork.

At the edge the reef stretches downward to a sandy 35 meter deep bottom. In the north one finds massive boulders surrounded by small rocks and the waters are a bit shallower. The areas all around these boulders are covered in soft and hard corals and gorgeous sea fans.
This is a well known for its strong currents divesite, particularly at the top of the boulders, where it’s difficult to find shelter. Across the length of the deeper waters of the site however, one can more easily hide from the currents.

Many of our liveaboards will sail you to Shark Fin Reef where you can continue your exciting scuba dive trips, testing your skills and physique against these strong currents, while catching awesome views of vibrant marine life to be found in the site.

Similan Islands

The world famous Similan Islands Marine National Park, in the Andaman Sea of Thailand, consists of 9 stunning islands, all uninhabited. Besides the paradise found on the islands themselves, with amazing rock formations and beautiful white sandy beaches with crystal clear waters, the marine life in the underwater world is astounding.

Map of the Similan Islands Dive Sites in ThailandA variety of corals, soft and hard, house the wealth of aquatic life whose reputation has reached across the world. Fully protected under National Law, Thailand’s Similan Islands offer the richest and most diverse coral reefs to be found in the entire globe.

The Similan Islands provide the best grounds for rich and exciting liveaboard dive trips. This is the best place for you to begin your scuba diving adventures or indeed, to further advance your diving skills and certifications on board one of our luxury liveaboard vessels. Divided into Western and Eastern dive sites, the Similan Islands offer opportunities for unique and diverse dive trips, depending on what you prefer to see and experience.

It has crystal clear visibility and the currents around the rock formations are sure to leave you feeling excited and exhilarated, willing and ready for more.
The Eastern area on the other hand, well protected from the monsoon coming from the south-west boasts white sandy beaches that stretch underwater to a wealth of hard and soft corals. The currents are never strong in this area, which makes diving and navigation quite simple and easy.
