On Malaysia's west coast, Langkawi is an archipelago made up of 99 islands. 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.
