Two hours by boat off the coast of Samui is the Ang Thong Marine Park, a National Park consisting of forty one islands, all of which appear to be covered in lush tropical forest bordered by untouched golden beaches. This place was the inspiration behind the best selling novel The Beach by Alex Garland and it's easy to see why. The Emerald Lake is a landlocked salt water lake bordered by high limestone cliffs on all sides and therefore hidden from view until you ascend the steep steps over the cliffs. This lake is preserved and swimming is prohibited. Our tour then took us to Ko Wua Talab, the largest island in the archipelago and the base for the park's headquarters. A viewpoint at the top of the island gives spectacular views although the climb is a very challenging yet enjoyable one. This island is the only place where staying overnight is allowed, and even then it's limited to three days and there are only a handful of huts.
