Hike up to the Black Rock Viewpoint
Black Rock is a stunning viewpoint near Nai Harn Beach where you will be able to get an unmatched panoramic view of the entire southern coast of Phuket, providing an even better view than from the Big Buddha statue. From this viewpoint, you will have an incredible vista over Nai Harn Beach and Promthep Cape as well as all the other small islands around Phuket. It is probably one of the best viewpoints in Phuket and a must-do if you are in Nai Harn.
There are 2 ways you can get up there. First, you will have to ride your moped to a dirt road leading up to the Black Rock viewpoint, and from there, you have 2 options. You can either walk the length of around 2 km to the trailhead to the Black Rock viewpoint or you can hire one of the taxi drivers there to take you up on their pick-up trucks. Unless of course, you are still feeling active and don't mind hiking a little further. There is another cool place to hike to beyond Black Rock Viewpoint called Krating Cape which is a better place to watch the sunset than at Black Rock.
