On the contrary, it is also pointed out that tourist when using these paths have trouble reaching the right destination. This paper describes a convenient trail guide system which provides a suitable path for each skier. This system was developed as a java applet for the aim of an easy access even from a personal tablet or a smart phone anywhere/anytime. Since the protocol is simply using backtracking algorithm, profitable and applicable for any platform, system can be easily modified and upgraded.
