From Malaysia, we headed north to Thailand, hopping from island to island in the Andaman Sea like birds (by plane and boat), never setting foot on the mainland. Our first stop was Koh Lipe (koh means island in Thai). It's a small but rapidly developing island with beautiful beaches of white powdery sand. Koh Lipe is located amid larger, mountainous, uninhabited islands of a national marine park, which provide a green backdrop for its sea views. There we snorkled, walked on the beach, took boat trips around the nearby islands, and volunteered for a big beach cleanup project in the national park, which picked up 125 bags' worth of trash that had washed up on shore!
