Taxis that are even more unusual, though equally convenient, are the river taxis that ply the Chao Phraya river. Some ferry passengers across the river (2 Baht), while others run the route to various landing stages on both banks, going up as far as the northern suburb of Nonthaburi. Fare ranges from 5-20 Baht per person, depending on distance. Signs at the landing piers are posted in both Thai and English.
