Ko Yao Yai in Phang Nga Bay is the larger of the two big islands in the Ko Yao Archipelago. Its name simply means 'big long island', in contrast to its sister island Ko Yao Noi (Little long Island).
Two worlds meet here: On the one hand, you can still get to know the old Thialand here, Thailand that seemed untouched before tourism came. On the other hand, some of the best hotels in Thailand are represented on Yao Yai.
The island offers some beaches, discovery tours by bike or moped, and of course some infrastructure, albeit much more rudimentary than, for example, in Phuket.
