The "canopy walk" in Penang Hill is an added attraction to its natural beauty and invigorating air.  However be prepared to walk over a kilometer along a quiet tarred road high up in the hill to arrive there. Awe-inspiring view of Georgetown all the way. But make sure you don't walk all that distance for nothing if it is closed for maintenance. Ask at the counter of the funicular railway when buying your train ticket for Penang Hill.
