Find Liveaboard Diving & Day Trips

While the vast majority of the trips that we sell are for overnight and liveaboard diving cruises, we still offer a good selection of diving day trips at the Similan Islands, Koh Bon, Koh Tachai and Richelieu Rock (which is in the Surin National Marine Park). Day trips enable guests to enjoy the comfort of their Khao Lak hotel or resort, and they’re ideal for those who don’t like sleeping on a boat or who have family or a partner who doesn’t want to join. Almost all of the diving day trips offer two dives, because there isn’t really enough time to squeeze in three dives, plus all the travelling required. With Richelieu Rock as the exception, the day trips’ two dives are nearly always at different dive sites, even if on the same island. For example, Koh Bon has at least two dive sites, as does Koh Tachai. Prices are very comparable from one boat to the next, and there isn’t the wide selection of prices that can be seen on our liveaboard boats. All our Similan diving day trips depart from Khao Lak, and they are not suitable for guests who stay in Phuket the night before departure. The vessels used for transfers and for diving vary, but all need to rely on speed to cover 60km or more each way.

Itineraries for our Similan & Richelieu Rock diving day trips are quite similar. All leave from Khao Lak in the morning, and return before sunset. Guests are collected from Khao Lak hotels and resorts at set times (usually) for free. These times vary depending on the boat’s departure time and pier, and how far away from there the guests’ hotels are.
