Phang Nga Bay's limestone caves comprise distinctive features that make them stand out. Once inside, tourists can see breathtaking emerald green walls, adorned with plant life and illuminated limestone formations. Some caves have an opening in the top, which allows sunlight to filter through, creating an ethereal yet mesmerizing natural lighting effect. The caves are a haven for bats, macaques, and birds. However, the most exclusive feature is the 'hongs', hidden lagoons within the caves that kayaks and canoes can access during low tides. Show more
