Thailand Diving – A Quick Guide

Thailand is where I’ve lived on and off since 2004. The diving here is relatively cheap and great, particularly on the west coast in the Andaman Sea. Here is a quick overview of diving in Thailand to help you decide where to visit.

Feather Star At Koh Bida, Thailand

Best Places To Dive in Thailand: The Similan Islands and Southern Thailand’s dive sites are my personal favourites. The links go to articles and trip reports I’ve written about each area. Pattaya is great if you are into wrecks. Koh Tao is great for learning to dive, a big backpacker party scene and also a growing tech diving industry.

Thailand’s Best Dive Sites is a useful introduction and also Whale Sharks In Thailand: Where To See Them.

  2. Hi Walter
    with 2 weeks, you have plenty of options for diving in Thailand, Malaysia and Indonesia – the issue is which areas to choose, as you can’t do all of them in 2 weeks! It also depends a lot on your budget.

    If money is no object, I would go straight to Indonesia and do a Komodo trip or Raja Ampat trip – both are usually around 10 days long so will take up your whole vacation period. Both Komodo and Raja are amazing and to do one of these big trips is a magical experience.

    If you want to see Thailand, a 4 day Similan Islands trip is a must (see my friends at for a good value liveaboard) and also Southern Thailand around Koh Lanta and Koh Phi Phi. That’s another 3/4 days.

    You could fly down to Tawau in Malaysian Borneo and head out to Sipadan, Malaysia’s jewel in the crown – you can get to Tawau on AirAsia via Kuala Lumpur so it’s not too expensive. However, you’d need to ensure you have a booking with a reputable Sipadan agent so that you get the necessary permit to dive at Sipadan itself.

    You can also fly from Bangkok straight to Bali with AirAsia very cheaply – Bali has some great dive sites and is also an amazing place to hang out and relax.
