On Penang Hill you can pay 50 ringgit extra to enter 'The Habitat'. It's a winding trail in to denser jungle with lots of info about wildlife. Sadly we didn't see any of the dusky leaf monkeys, giant squirrels or langur monkeys but there were lots of information boards telling us of the types of animals which can be found. We saw a lizard, lots of big butterflies and of course there was the constant buzz of the jungle. Although I didn't see much wildlife, it was just nice to stroll along and enjoy the atmosphere of the place.
The highlight was Treetop Walk, a rather futuristic looking circular aerial walkway which marks the highest point on the island. The views are excellent but make sure you've got plenty to drink as it's very exposed to the sun.
The Habitat has an excellent souvenir shop with some quality items (no tacky souvenirs here!), plus a café and toilet facilities.
Included in the ticket price is a golf-style buggy back down to the main touristy bit of Penang Hill.More
