Why not go for a parasailing at Batu Feringhi Beach. I am not sure how much the operator charge you but it something that you don't want to miss when in Penang.
It's water and air activity, the parachute is tied to a boat and once you're ready the boat rider will pull you up to air.
The ride will takes about 3- 5 minutes and you will have a good bird eye view of Batu Feringhi beach and it's vicinity.
Just remember to pull the parachute correctly during your landing. Something that I might want to try myself on my next trip to Batu Feringhi, Penang.
