Due to thick forest there are many monkeys in the area. You would find groups of monekys every where on trees doing some times really funny acts. Watching them would be fun and if you offer them some thing to eat then they would quickly come towards you and take what you offered.
Fondest memory: Monkeys some time do really funny acts. You would enjoy watching them for sure. Please make sure you do not irritate them otherwise you would be in trouble because when monkeys get angry, they can attack you.
Do feed monkeys on your next trip to Nathiagali and do not forget to take their photos. I hope you would go back home with really nice memories of Nathiagali. :-)
