Phuket, in case you don't know, is full of hills. The highest point in Phuket is over 500m above sea level (I hiked up there a while back), while the Big Buddha sits over 400m above sea level. Around the coast, the roads wind up and down the hills, sometimes climbing up from sea level to give great views. Phuket has many viewpoints, some with names, some without, but the best known and most visited is the 3 Beaches Viewpoint, also called Kata Viewpoint, though the sign by the road says "Karon Viewpoint". And the view is indeed a good one....
