This picture explains why you have to duck and lie down when the canoe goes through some of the caves...
The first lagoon in Panak island, at the other side of Bat Cave. We can see monkeys clinging to the cliffs of this lagoon. There is another passage leading to another lagoon with mangrove trees.
The exit on the other end of Bat Cave is literally a tight squeeze. This exit leads to a lagoon in the middle of the Panak island.
It's going to places like this that makes this trip so special. This is the second and last cave canoe trip. After this, it's off to James Bond Island!
Phang Nga Bay is a part of the James Bond island trip. But it's really nice. Going to canoe get ready to get wet. So you better take off your pants/shorts if you want them stay dry.
There are several excursionns possible from Phuket, i would reccommend a tour of the arcipelag as it offers really great views.
