The only real settlement is on the main island, Pulau Langkawi. This popular beach destination attracts divers from around the world to explore the sea life, and after being declared a duty-free zone back in the '80s, it has become a favorite shopping spot for visitors seeking cheap booze. You'll find sightseeing attractions—such as national parks, a cable car ride, and a large aquarium—throughout this island of lush rainforests. However, it's the long stretches of sandy beach that attract most visitors to this tropical paradise.
