Maeklong Railway Market is a traditional Thai market selling fresh vegetables, food and fruit in the province of Samut Songkhram, southwest of Bangkok. What makes the market special is that it occupies part of a train line. A few times a day, a train runs directly through the market 

 Here you can witness a train run through the Maeklong market seven times a day! It is definitely something worth seeing when in Thailand and I highly recommend making the trip from Bangkok, Thailand. 

 Boating, water skiing, wake boarding, canoeing, kayaking, water polo, diving, scuba diving and snorkeling .

 Pattaya Beach is the most famous beach in Pattaya. It is a center of marine activities for those who come to rest such as sunbathing and water sports. The whole 3 kilometres along the beach is full of hotels, restaurants and souvenir shops. 

You can  go and snorkel around Pattaya far islands. Because visibility is better. You will be surprised, by the abundant marine life and corals you will see while snorkeling in Pattaya. Pattaya Snorkelling, in fact, is also a very easy, fun activity! 

A UNESCO World Heritage Site since 1991, Ayutthaya is a riverside city founded in 1350. Destroyed in the 18th century by the Burmese, it was once one of the world’s giant urban and cosmopolitan centers.

After the capital was burned to the ground in 1767, all inhabitants of Ayutthaya abandoned the city. Although never rebuilt in the same location, it remains as an extensive archaeological site of multiple Ayutthaya temples.
