Go to James Bond island at Phang Nga Bay, near Phuket

You should go on a day tour of James Bond island by boat. It's a very popular spot but you can't miss it, it's spectacular. The limestone caves with stalactites and bats (you're driving through some of them), the mangrove forests, the fishing village raised above the water on stilts, the scenic views of the small mountain islands we were passing by and the James Bond island itself combined to make a beautiful experience for us. I can't hardly wait to go again and this time I'll try the night tour around the caves. If you want to book a tour ask at your hotel desk, there are a lot of touring companies on Phuket island and the hotel concierge knows them. The tours cost around 1000Baht.
