Scuba diving and snorkeling in Krabi

With around 160 kilometres of coastline meeting the emerald Andaman Sea, as well as its myriad islands, Krabi boasts more than 32 dive sites and countless more snorkeling spots. If you are fascinated by life underwater, Krabi offers a rich marine environment, with superb corals, pinnacles, underwater caves and rock formations. Leopard sharks, turtles, and even dolphins are regularly spotted.

The majority of dive locations are shallow and thus suitable for all levels of divers, from beginner to pro. Any number of PADI-certified dive schools exist to teach newbies, either on a day-long ‘Discover Scuba Diving’ trip, or a more serious Open Water course, upon completion of which you will receive an internationally valid diving licence. Courses are taught in most major European languages, plus Japanese and Thai. We have a separate article with advice about choosing a dive school in Krabi, plus the range of courses on offer.

Those who are already qualified can go on ‘fun dives’ with knowledgeable, locally-based guides, or further their existing skills with the full range of PADI courses and specialities, right up to Instructor level. Krabi provides a more laid back and less intense environment than the “dive factories” over in Koh Tao on the Gulf coast – not to mention much better diving.

Another plus for Krabi as a place to base a diving holiday is that it offers a wide variety of other activities for non-diving companions. Friends and family can even join the dive excursions as a snorkeler or passenger, and these trips can offer a good opportunity to visit islands and reefs not on the usual “island cruise” itineraries. Though there are no beach stops on these trips, the boat is a comfortable cruise vessel with open and covered decks on which to relax throughout the day.

We’ve also listed a few dedicated snorkeling cruises below, that also go out on larger cruise boats. If you are really serious about snorkeling and would like to see more than the same old, often badly damaged, reefs on the mainstream island-hopping trips, we highly recommend these outings – the premium price tag is worth it for those who are into marine life.


If you want to do a “real”, dedicated snorkeling excursion, with lots of tropical marine life guaranteed, we list your options below. You’ll also find options to book fun diving (for qualified divers only) and the popular one-day “Discover Scuba Diving” course. For information on longer courses, please contact us directly.
