The Floating Market is a floating bazaar where vendors sell their products in their little boats. It is somewhat outside the city. The busses take off from around the National Palace, usually in the morning.
Wat Arun is a wonderful sight to behold, both from inside and outside. Its name can be translated to “The Temple of Dawn”. Trust me, you would want to find out why by yourself!
Tiger Temple is not as famous as the other places. But that was one of my most thrilling experinces ever. It was a 3 hours drive from Bangkok but it was worth it. Budhist monks and some volunteers around the world keep, feed, clean tigers in this budhist tample. And they let tourists touch them. You can have a picture with them too. There are real good tours from city you can join, visiting tiger temple. Most of them start early in the morning.
