Balinese Macaques at the Sacred Monkey Forest in Ubud, Bali, Indonesia This female has the best teeth I've ever seen on a wild monkey...
Balinese macaques are all over the island of Bali. Some are friendly; most are not. I'd strongly recommend against interacting with any of them. And, I'd also highly recommend leaving anything of value, or anything that dangles, back at the hotel.
