Koh Ngai , Koh Muk , Koh Kradan (plus many others)
Koh Lanta is a relatively chilled out destination for the more selective tourist. The west coast has numerous beaches offering ample options of restaurant, bars and beach massages .
A little further south are Koh Ngai, Koh Muk & Koh Kradan. These 3 islands have minimal infrastructure on them, but all offer something different, from good snorkeling spots, perfect bays to watch the sun set, or beach bars to grab a cocktail from.
The main attraction here has to the Tham Morokot (the Emerald Cave). This is an 80m swim through a pitch black cave entrance, which then opens up into a ‘Hong’ (meaning ‘room) in the center of the Island. This ‘Hong’ is completely enclosed on all sides by the tall limestone cliffs covered in foliage. This is a must see, an unforgettable experience.
