On Koh Hua Tah Lap, one of the islands of Moo Koh Angthong, a National Marine Park in Surat Thani Province, there is a huge cave, known as Tham Bua Bohk, i.e. the ‘Cave of Waving Lotuses’ or ‘Waving Lotus Cave’.

It is yet unspoiled by mass tourism  and hence there is no real hiking trail into this rather large cavern, making a visit the more adventurous and much less touristy.
