Trat, Thailand's easternmost province, is located 315 km from Bangkok and shares a long border with Cambodia.
It is best known for its beaches, particularly those on the islands of Ko Chang National Park. The area was passed back and forth between Thai and Cambodian/French sovereignty over the years, and a significant victory for the Thai navy over the French was won at the southern end of Ko Chang in 1941.
Beyond Ko Chang, Ko Mak and Ko Kud are inhabited and have beautiful beaches but can be difficult to get to during the monsoon season.
Like neighbouring Chanthaburi, Trat has a rich gem trade as well as thriving agriculture and fishing businesses.
