Johor Bahru is the state capital of the state of Johor and the second largest metropolitan area in Malaysia. Most tourists don't stop here and just pass through the city on their way to or out of Singapore. JB is a major local transportation hub however. Since it is just across the causeway from Singapore, some travellers use it as a hub to visit Singapore from here (lower accommodation prices) or to board the train, bus or airplane.
Alor Setar is the capital of the state of Kedah. It is a transit point for trips to Thailand and to Pulau Langkawi. The ferry to Langkawi departs from Kuala Kedah, just few minutes outside of Alor Setar. The city is a center of Malay culture and is surrounded by paddie fields .
