Exploring the Ancient Forest and Vibrant Natures in Rayong and Chonburi Provinces

Rayong and Chonburi provinces are located on the east coast of the Gulf of Thailand, close to Bangkok, and are recognised as one of the most popular tourist destinations in Thailand. These areas boast abundant natural resources and are celebrated throughout the country for their excellent natural environment, delightful beaches, tropical fruit, and fresh seafood. They are popular coastal provinces among Bangkokians who seek the nearest escape from hectic weekly schedules to the seaside. Besides tourist attractions, these provinces are known for their natural fertilisation, which is defined by the rich history of nature in the tropical climate. It turns out that Rayong and Chonburi became home to a huge agricultural industry area in terms of both economic fruits and valuable natural resources.

The Natural History Section of The Siam Society has obtained special permission for a limited number of participants to join this study trip, which will be led by Thailand’s outstanding naturalist and scientist, Dr Weerachai Nanakorn, 1st Vice President and Honorary Leader of the Natural History Section.
