Yep you have to walk to sueno azul area for both the bus to santa pola and the bus to Alicante, its not a long walk from up the top only ten minutesish, one goes from one side of the road next to sueno azul and the other goes from the other side, cant remembr which is which but timetables are also on the stops and they run regularly, lovely buses, inexpensive and definitely worth using.
