There are 3 view points. Addmision is 30THB.You can arrive there by following signs say view point from city center.picture is view point 1&2.
We were undecided on whether we wanted to pay the 30baht entrance fee and walk up all those stairs with little ones but we did it in the end. The views are very nice and although the landscaped entrance with fruit shaped seats is a bit odd, the kids loved it. Viewpoint 2 is where you get the panoramic view over PhiPhi island.
