On the Chao Phraya.
Taking a boat trip or ferry ride along Chao Phraya River is one of the best ways to explore Bangkok. It's extremely cheap to hop on board with locals (which often include orange robbed monks) cruising down the river with wonderful views of the Bangkok, Thailand. Boats are a great way to get around the famous riverside area with its many historical attractions, and to explore the 'klongs' (canals) for a glimpse of yesteryear Bangkok. Several kinds of boats (express boats, river taxis and tail-boats) run up and down the Chao Phraya River, connecting with the local suburbs on the Thonburi side and along the river, while ferries can be used to cross the river at various points.
