Being able to enjoy the best of both worlds—luxury island life coupled with convenient access to some of the most well-known dive locations in the Gulf of Thailand—is one of the biggest benefits of visiting Koh Samui.

World-class diving sites like Sail Rock and Koh Tao are just a short, picturesque speedboat trip from Samui.

It is frequently recognized as one of Thailand’s best diving sites and is located mid-way between Samui and Koh Tao . This diving site offers you the excitement of exploring magnificent underwater landscapes without sacrificing comfort or convenience, and it’s only 50 minutes away by speedboat from Koh Samui.

However, Koh Tao tends to draw a younger, more frugal clientele, particularly backpackers and tourists seeking reasonably priced dive instruction and modest lodging. Although the island is charming in and of itself, individuals looking for a more relaxed and rustic experience are the target audience.

You may get the best of both worlds by choosing to stay in Koh Samui. After a day of diving in Koh Tao’s crystal-clear seas, you may retreat to the plush surroundings of a bigger, more established island. You may return to Koh Samui in about 1.5 hours by speedboat and take advantage of its renowned upscale resorts, exciting nightlife, and fine restaurants.

If you decide to base yourself in Koh Samui, you will still have easy access to some of the best dive sites in Southeast Asia, as well as premium accommodations and the island’s cultural offers. For divers looking for an exciting underwater experience combined with luxury on land, Koh Samui is the ideal choice.

Getting to Koh Samui

One of the key advantages of Koh Samui is its accessibility. As one of Thailand’s most popular islands, Koh Samui is serviced by an international airport, offering direct flights from Bangkok, Phuket, and other major Asian cities such as Singapore and Hong Kong. This makes getting to Koh Samui quick and convenient, whether you’re coming from within Thailand or abroad. Upon your arrival, the island’s infrastructure is well-developed, offering a diverse array of transportation options, including private transfers, taxis, and vehicle rentals, to facilitate your exploration.

Conversely, the journey to Koh Tao is somewhat more adventurous. There is no airport on Koh Tao; therefore, the sole method of transportation to the island is by ferry. Initially, travelers must travel to either Koh Samui or Surat Thani on the mainland. Subsequently, you will require a ferry ride, which may require 1.5 to 3 hours, depending on your starting point. Lomprayah fast ferries is the biggest ferry operator in the region and you can book directly on their website. 

Staying on Koh Samui will provide you with the convenience of direct flights and the comfort of arriving at a well-developed island. It is effortless to board a watercraft from Koh Samui and access nearby dive sites, such as Koh Tao, without the need to navigate the additional logistics of ferry transfers. Koh Samui provides an ideal combination of accessibility and adventure for those who desire a seamless travel experience that includes the opportunity to investigate multiple islands.

The additional costs for fuel, boat maintenance and insurance provided on Koh Samui contribute to the higher price.
