Book a longtail boat from Sunrise beach for about 100THB per person. Remember to arrange with the captain when and where you want to be picked up again. When reaching the beach on Adang Island, walk to the right among the bungalows and you will soon find a sign that points to the path. If you cannot find the sign, there is a ranger station in the area where you can ask for directions. There are 3 stops on the way to the viewpoint, each providing an increasingly better view of Koh Lipe. Please note that it is not advisable to go trekking after it has just rained; the path can be slippery and dangerous.
Anyone in good health can do this trek. The key is not to take your time, wear good shoes, and bring lots of water. Some parts of the path will be light jungle and others bare rocks. It is not recommended that anyone try to walk this path with bare feet or flip-flops. The trek can easily take 2 to 3 hours.
