Tawau is known for its cocoa production, and the one-of-its-kind Teck Guan Cocoa Museum showcases the development of this industry in the region. The museum has a cocoa processing plant and manufacturing factory within its compound, and you could take educational tours and learn about raw cocoa processing. In addition, there are cocoa products and chocolates available for sale, and you can also sample a few of them. The museum needs advance bookings for visits, however.
