I know Khao Yai Ntl Park very well and have spent quite a bit of time there , hiking and exploring . There are definitely wild elephants , and some tigers too. All sorts of wildlife in those cool mountains, the closest natural forest getaway from Bangkok. It’s beautiful. But I always rented a cabin and never tent camped . For the very reason if the wildlife . You could end up with a cobra in your tent. I can still.hear the sound of the deep Thai jungle , at night, in my head. I would hear the sound of the occasional roar , or elephant trumpeting. Awesome stuff . Gibbon troops singing in the forest canopy .
I bet mating season was hell.
