Khao Lak is a tourist-oriented destination in Thailand, which is part of Takua Pa District in Phang Nga Province. The name “Khao Lak” literally translates to “Lak Mountain”. As a site that is popular with tourists, it has plenty to offer its tourists in terms of things to see or do. Aside from the beautiful natural resources found within the Khao Lak Lam Ru National Park, but the major attraction is definitely diving.


Khao Lak is recognized as one of the most popular diving destinations in Thailand, among a long list of options. Its proximity to the famous Similan Islands can be attributed to that. Since most of the dive sites in Khao Lak are located offshore, it will require a full day trip to be able to maximize the dive experience, or if you want to venture a little farther away.

Khao Lak is a great choice for divers who wanted to see manta rays during their dive. Whale sharks are also among those you can spot, aside from manta rays. The timing of your dive has a lot to do with what you can encounter underwater during your exploration.

The proximity of this diving destination to Andaman Sea means that it is strongly affected by the conditions on this ocean. The water temperature comes with an average of 28-31 degrees Celsius throughout the year. From February to March, expect colder water temperatures as the nutrient-rich currents from the deeper portions of the ocean swell up. 

The good thing when the water temperature gets cold is that it is when manta rays and whale sharks tend to show up.

Khao Lak is located about 60 kilometers north of Phuket. It is on the western coast of Thailand and measures at about 20 kilometers on the Andaman Coast. The area is known for having low, coastal areas.

This area was one of the ones seriously devastated by the tsunami that mainly hit Phuket in 2004. However, the island has since recovered and is slowly gaining its ground as far as preserving the natural beauty of the ground. Unlike Phuket, this has more of a family-friendly environment (whereas Phuket is more suited for party-goers). It offers a completely relaxed feel with the mountains serving as a beautiful natural backdrop to the tree-lined shore. There are also several protected areas in Khao Lak.
