Why should you go there and how do you do it right?

The National Museum of Royal Barges is located in a former dry dock on the north bank of Khlong Bangkok Noi in Thonburi and houses eight of the 52 barges of the Royal Barge Procession on the Chao Phraya River. The centerpiece is the Suphannahong, the king's 46-meter-long barge, adorned with a golden swan at the bow and crewed by 50 rowers and two helmsmen. Also moored alongside are the Narai Song Suban, the Anantanakkharat, and the Anekkachatphuchong. The Fine Arts Bureau restored the dock and barges after the bombings of World War II, and the museum opened in 1972.

It's a large boathouse that can be explored in half an hour. Therefore, it's best as a stopover on a Thonburi Canal cruise by longboat, which is included in most canal tours. On foot, it can be reached via narrow alleyways from the Chao Phraya Express dock at the Phra Pin Klao Bridge.

The art department does not publish the current admission price online, so you should bring cash for your ticket. According to Google, the museum is open daily from 9:00 AM to 4:30 PM.
