Richelieu Rock, Koh Tachai & Surin Islands 7 dives

Our 3-day/3-night trip visits the more adventurous dive sites in the north:


  • Koh Tachai – There are several dive sites on this island. From gentle reefs to rock walls, plus one of the most impressive dive sites in Thailand. Between January and May, manta rays or whale sharks sometimes visit to feed on the rich currents
  • Surin Islands – picturesque and quiet, close to the border with Myanmar. Five islands with a variety of granite boulder sites and superb coral reefs. Plus stunning beaches and great snorkeling in the shallows
  • Richelieu Rock – a submerged pinnacle in the middle of nowhere. This dive site is legendary for first-class diving and the diversity of fish life. With the possibility of a whale shark or seahorses, if you’re lucky!

Your Trip Supervisor will give a quick pre-departure briefing before we leave the dive center. Our southern trips depart from Thap Lamu harbour, which takes about 20 minutes by taxi. Our northern trips depart from Khuraburi harbour, which takes about 1 hour 20 minutes by air-conditioned minibus.

Onboard, we will show you to your cabin where you can stow your luggage. The Trip Supervisor will then give a boat orientation and briefing on the middle deck. The journey to the islands takes about 4-5 hours to the Similans or Koh Tachai, 3-4 hours to the Surins.

Return on the final day :

After the second dive on the last day of your trip, we head to the nearest harbour. From the Similans, we go to Thap Lamu harbour. However, from Richelieu Rock, we go to Khuraburi harbour. We serve lunch on the journey and you’ll have time to relax more as well as pack up your things

Before we arrive at the jetty, your Trip Supervisor will collect any outstanding money for beer, courses, logbooks, etc. Should you wish to, you can leave a tip for the boat crew in their private tip box. We will also try to get a group photo as a memento of our fun trip together

We arrive back at the dive center at about 16.30/17:00hrs. We’ll take a few minutes to return your valuables from the safe and any luggage you have stored with us. Then we will take you back to your hotel in our taxi
