Fruska Gora, also known as the "Holy Mountain" of Serbia due to the abundance of monasteries housed within it, is a must go destination. It is one of Serbia's largest National Parks with an extensive road network, interesting as well as challenging biking routes and a great number of places to explore and enjoy. Its center lies just 45km from the MotoCamp, and it is partly on the way to Novi Sad, another worthwhile visit.
