Phu Quoc is a mountainous island that's covered in rain forest. The whole interior is government property and a preserve. Not too many of these in Nam. During the war there was a POW camp run by the ARVN's on the island, so it saw virtually no fighting in it's interior. It's one of the few places you can go on a hike in the jungle and have a good chance of spotting monkeys and other wildlife. Also, not having to worry about left behind booby traps or ordinance. We were hoping to spot some monkeys on this short jaunt from the car. Didn't see any, but it was a beautiful spot none the less.
