Perhaps the best thing about Koh Hong's immense popularity is the fact that the other islands that make up this extensive archipelago remain largely unexplored. Hundreds of Flying Fox, or Giant Fruit Bats, roost on one of these isles. Hanging like elongated fruits from the branches of trees atop karsts, they stretch and yawn at sundown, then fill the sky with life as they set off inland on 1.5 meter wings for the rich tropical fruit bounty of Khao Phanom Bencha's forests.
