You could just take a local boat from the pier. It'd be a great way to view the city. I don't think you'd need to book a speed boat prior but I'm not 100% sure

Chao Phraya Dinner Cruise with Private Transportation by Travstore Travel Management. Set out onto the Chao Phraya River for a romantic evening that takes you past the wonders of ancient and modern Thailand. This cruise lets you dine on exquisite Thai and international cuisine and enjoy the soothing sounds of saxophone and violin as you glide past the glittering temples of Bangkok. A private, air-conditioned vehicle carries you from your hotel to the banks of the Chao Phraya, the great river that flows through the center of the city. There, you board the elegant cruise ship, relax with a welcome drink, and settle in for the voyage to see the sights illuminated at night. Check out spectacular landmarks like the temple of Wat Arun, with its towering stupa-like pagoda, and the golden spires of the Grand Palace.

Devi fare un tour con la cena, basta rivolgersi alle agenzie che stanno direttamente ai pirti di attacco. Ce ne sono molti.

Dinner Cruise on the Chao Phraya River costs around 990 THB. You can book online or through your Travel agent, at the Hotel where you are going to stay. It may increase to around 1200 THB when they arrange to pick from the hotel and drop you back after the dinner cruise is over. It is a wonderful experience to have the dinner cruise.

Both local and tourist boats are not friendly strollers. You may go for a private boat so that you have sufficient time to hop on and off the boat.

Your hotel should be able to book this for you, alternatively you can book this from one of the tour offices located just before you turn onto Khoasan Road. Make sure you use a tour office rather than from one of the many stands selling tour tickets nearby.

Hi we got our boat trip outside Sky Train station Saphan Taskin on the Silom line which is right on the river. We was staying in the Shangri La so it was just a short walk for us. We got our boat from there, which is in the right hand side of the bridge if you are facing the river. The were several choices and we went for the two hour Longtail boat trip which takes you along the river and then through the canals and you can see how the Thai people live and see large lizards like little dragons, but you can get taxis to see the places and temples. We saw the temples and palaces by taxi, we hired a cab for one day and he took us to them all and waited at each one for us. As you in Bangkok it good to see them both but the Longtail boat trips are great value for money Hope this helps
