Samutprakarn Crocodile Farm which is the largest in the world is located to the East of Bangkok, aprox 30 from my home in Thonburi.  To get this place is possible just either by bus or taxi.  Nevertheless if you take the bus you must catch a taxi at the bus terminal.  So for the most convenience it is recommended to take a taxi.
On the way to the Crocodile farm you are going to see part of the spider net of the Rama 9 bridge linking between Bangkok and Samutprakarn.  Although the traffic jam in Bagkok, I am surprised at how modern the Bangkok's spider net is.

The entrance fee for adult is Baht 60 per person for Thai and Baht 300 per person for expat (USD 10).

After you come in the entrance gate, firstly you will see a Dinosuar Museum with life-size exhibits and skeletons. Not only you will see the crocodile farm but also you will enjoy the zoo.  You can take photos whatsover as many as you want. However, taking the photos with the animals (tiger, monkey, exotic bird) will cost Baht 200.  Well, I think, it is a good way to raise money in order to support the animals  of the zoo.  You can also feed them with the food provided by the zoo, which costs about Baht 20 (less than USD 1).

This farm is open every day and one of the most attrative show is the Crocodile show.  This show is organized almost every hour and lastes almost 30 minutes.  During the performance my wife was totally scared and still when the guy was putting his hand and his head into Crocodile's mouth.  Any way, some people like this show and even they not only have fun but also throw the money to reward the performers.

The last show we saw that day was The elephant show. This was totally amazing. How huge animales like elephants can perform such as tender acrobat!!!!!! It was astonishing when they play mouthorgan, or when they walk on the string like skillful human acrobat!!!!
