Koh Tachai is a small island – just 12 km² – located 50km west of Phang Nga coast. Belonging to Mu Koh Similan National Park, it has been preserved for centuries from any human intervention due to its remote location, at least until early 21st century. Offering outstanding underwater landscapes – Tachai Pinnacle is the most famous dive spots around – it became a must-stop place on the journey of scuba diving live-aboard boats heading to Richelieu Rock from the Similan Islands (Koh Tachai is situated right in the middle of these two world-famous dive spots).
It didn’t take long for the Thai tours industry to realise that Koh Tachai was offering an excellent alternative to the Similan Islands for day trips by speedboat. With white powder sand beaches, endemic fauna and flora species, and crystal-clear waters, Koh Tachai is indeed a tropical paradise.
The east coast of Koh Tachai is, in its central part, a long beach fringed by trees offering shade to the visitors, while the west coast of the island is rocky and offers no landing point. A Thai Rangers’ camp with basic facilities – toilets and restaurant – permits tourists to enjoy a minimum of comfort. Most of Koh Tachai’s visitors stay on and off the beach to sunbath, swim and snorkel, while the most adventurous try to reach the viewpoint on the west coast of the island that can be reached via a steep path located toward the northern end of the beach.
The closest and most convenient port of embarkation to Koh Tachai is Baan Nam Khem (20km north of Khao Lak) yet, due to the tidal conditions, it happens on some days that departures are moved to Tap Lamu pier which is a deep-sea port situated 5km south of Khao Lak. The only way to get there is to join a day trip that you can book at any of the travel agencies on Khao Lak.
