Daily Similan Diving Schedule 2026 – 2027
Every day (well, almost — Tuesdays are a rest day) the Wave Rider heads out from Khao Lak to the best diving the Andaman has to offer: the Similan and Surin National Parks, including world-famous Richelieu Rock three days a week.
Two dives, lunch on board, back on the beach in time for sunset. Here’s what’s running, when.
Wave Rider Weekly Schedule
Journey time runs 50 to 80 minutes, depending on conditions and the site. Tuck into a home-cooked Thai buffet lunch after the first dive, then back in for dive two once you’ve had your surface interval. We’re back at the pier with time to fill in your logbook — and you still catch the sunset.
All day trips from 5,300 THB per diver, excluding national park fees and equipment
