For foreigners staying in Thailand long-term, the island of Penang in Malaysia is one of the best places to make a visa run. The Thai consulate is small, casual, and efficient. There is a great variety of food available, especially Indian food. And the old Chinatown in the heart of Georgetown is one of the most interesting and authentic you’ll find anywhere.
There’s no need to follow a particular walking route—just step out the door from your hotel or guesthouse and wander aimlessly through Georgetown’s Chinatown, soak up the atmosphere and see what there is to discover.
