For hardcore divers looking to devote their time to being underwater, the Similan Islands are the place to be. Famous for good reason, divers in the Similan Islands can expect to see some of the best diving experiences in Thailand in just a few days. Most of the trips are four nights, which is the recommended length of time to truly appreciate the beauty of the area, but there are shorter trips for travellers who don’t have that much time.

Most suitable for experienced divers due to the length of the trips and likelihood of currents at the dive sites, most companies will require either an advanced certification or make you take the course while on the boat. However, the incredible visibility and access to rays, sharks, octopi, and a range of fish definitely make it worth your while. The best time to see sharks and rays is February to April, but other marine creatures can be seen year-round.

Most trips leave from Khao Lak, but there are some available from Phuket and Ranong as well. If you’re an experienced diver keen on spending your vacation underwater, definitely don’t skip out on the Similan Islands!
