Thailand is one of the most extraordinary freshwater fishing destinations on earth — and the species list is the reason why. Nowhere else in the world can you walk up to a lake and realistically target an Arapaima the size of a man, a Giant Mekong Catfish that could fill a bathtub, a hard-charging Amazon Redtail Catfish, and a surface-smashing Giant Snakehead all in the same day. Bangkok's fishing parks and wild reservoirs hold an incredible mix of native Thai giants and exotic imported species that draw serious anglers from every corner of the globe. Whether you have one day or one week, a target species in mind or just an appetite for something extraordinary — Thailand will deliver. Here's what's waiting for you.
