Ko Rattanakosin is the historic area in Bangkok containing many of the elaborate temples and sights associated with Bangkok. This area encompassing the historic structures is often referred to as the Old Town. The west side is bordered by the Chao Phraya River, the east side by a canal originally dug to serve as a moat for what was originally the fortified city and effectively makes this area an island (Ko). The area is full of characteristic buildings and some of its big attractions include the stunning Grand Palace, Wat Phra Kaew home of the Emerald Buddha, Wat Pho with its giant reclining Buddha and the peaceful Golden Mount overlooking the city. Many of the sights are walking distance from each other, so perfect to hit them in the morning before the heat really kicks in. If coming from other parts of town, the Chao Phraya River boat service can be useful to get to the area with Tha Chang (N9) & Tha Tien (N8) stops the most convenient.
