About Big Blue Diving Khao Lak

Over the past years, Big Blue Khao Lak has built an exceptional reputation for running first-class dive trips in the world-renowned Andaman Sea. They maintain this reputation through attention to detail, efficient scheduling, and a dedicated team who are celebrated for their high standards – ensuring smooth diving experiences while effortlessly creating a laid-back and social atmosphere. Dive leaders are conscientious and strategically organise dives to maximise everyone’s enjoyment and safety, putting extra care into catering to the specific requirements of photographers or divers of varying experience levels.

The dive centre’s custom-designed and well-appointed speedboat, Blue Dolphin, offers exciting day trips and can access the best local sites in an hour or less – including Jacques Cousteau’s favourite, Richelieu Rock. Big Blue’s two Khao Lak offices are open from October to April each year, closing during the monsoon when heavy rains and rough seas make diving in the Andaman Sea more difficult.



ZuBlu can assist guests in booking a variety of nearby accommodation to suit all needs and budgets. Possibilities include the casual and sociable Walkers Inn, the quiet Happy Lagoon Bungalows with its fantastic swimming pool, waterslide, and Jacuzzi jets, or Khao Lak Youth Club which offers a more secluded and intimate atmosphere. Jerung guesthouse is conveniently located directly in front of the Big Blue dive centre, or for a little extra luxury and comfort, guests can choose to stay at larger resorts such as The Haven, The Marriott, or Ocean Breeze Resort.

There are several stunning beaches around Khao Lak, including Pak Weep Beach and White Sands Beach – both offering picturesque settings and an array of wonderful restaurants. There are also many secluded waterfalls nearby, such as Tong Chong Fa, which are perfect spots for escaping the hustle and bustle and cooling off in the refreshing water. Tours to nearby national parks can also be found, which include jungle trekking, river rafting, and other outdoor pursuits. Traditional Thai massages and authentic home cooking classes are also popular pastimes which can be found in abundance in Khao Lak.
