Most Similan Liveaboards follow a logical route, starting from the southern section of the Similans and then slowly progressing north over the cruise duration. Starting this way means you experience the easier dive sites first, recommended if you haven’t dived for a while. Also the Similan liveaboard trip builds up to the highlight, Richelieu Rock which features later in the trip.

On the last day or 2 the route will head back down south to Tab Lamu pier near Khao Lak.

Each day consists of a similar schedule: 4 dives interspersed throughout the day amongst eating delicious fresh Thai food, sleeping and the occasional beach visit. For a more detailed account of a typical day on a Similan Liveaboard you can visit our sample itinerary.
