Places we NEED to go: which way to the beach?

Although I have traveled to many resorts which all claim to have white sandy beaches with beautiful blue water, I have yet to find a beach that has really blown me away. Every time we go somewhere new, the beach is one of the things that I look forward to the most. Thailand claims to boast some of the most beautiful beaches in the world, which is one of the many reasons I want to go there.

I have a cousin who visited Thailand a few years ago, and when she came back she told me about an amazing island in the Gulf of Thailand called Koh Larn. She said that it was one of the highlights of her trip, and after enviously going through her pictures, I decided that I had to visit this island if I ever set foot in Thailand.

Some might say... a beach is a beach is a beach. 99% of the time, I would agree with this statement, but the beaches on Koh Larn (all 6 of them) appear to be stunning and uniquely beautiful. For one, they're all coral beaches. You can see a lot of great things while snorkeling on the island. Inland on the island is a lush mountainous jungle where you can see wild life, and of course its also just pretty to stare at. The water really does seem blue in the pictures, and the beaches really do seem white. I can't confirm this yet, but if the testimonials I have found online are worth anything, then I don't think I'll be let down. Banana boating and parasailing are also offered at this beach, which pretty much put this beach over the top.

There's also just something about the idea of travelling to a "remote" (ok, maybe not so remote) island. It brings the picture of being a castaway to my mind, and is there really a bigger adventure than that?
