Go up to Penang Hill for a nice view of Georgetown, and visit some of the colonial places (if you are interested in that). There is also a snaketemple, butterflypark, botanical gardens (tropical-fruit farm) and a big Buddhist temple (Kek Lok Si).
If you like golfing make sure you visit one of the courses on the island.
Grab a few beers, and be sure to eat lots of food. Try Mustafas for Indian food (think it is on Lebuh Chulia street).
For beachlife head over to the northern coast (where you find most of the resorts). The westcoast of Malaysia is not good for snorkeling/diving, but you can still swim.
Even better (if you have time) - take the boat over to Langkawi. Arrange hotel/hostel when you get to the jetty at Langkawi, and relax on the beaches there. Check out the sky-bridge (it had not opened last time I was there, but it looks cool): http://www.langkawi-beaches.com/langkawi-sky-bridge.html over 7 years ago
Ohhh, I am so jealous, I love Penang.
I like the Batu Ferringhi area for relaxing by the pool / beach and for the watersports. The night markets are also pretty fun. There are heaps of restaurants to choose from along Batu Ferringhi, plus the Hawkers centres are great too. The food is just the best - cheap too!
Goergetown has some good shopping areas (I think I normally visit Prangin Mall, which has a good selection of shops). There are plenty of other shopping centres between Batu Ferringhi and Georgetown, although they are pretty pricey!
In addition to Znabel's suggestions:
Go for a drive around the island, see the sites, and even visit a traditional fishing village?
My parents visited Cheong Fatt Tze Mansion and thought it was pretty impressive.
I hope that helps you a bit. over 7 years agoAnswered by Erin Furness via Travellr.com
