This is the largest museum in Southeast Asia so you should set aside several hours at least for visiting this particular Bangkok attraction. It’s recommended for anyone who’d like to learn more about the intricate history of Thailand. Starting in pavilion one you’ll see some very nice exhibits that begin to summarise the country’s history. The rest of the museum is set over numerous buildings, some with more to offer, and some with better exhibits than others. Parts of the museum have benefited from refurbishment, while others would still benefit from more work, but overall the insight you’ll gain from visiting will help you have a better understanding of the local culture and more of an appreciation for the many things to do in Bangkok.
