Create a path between point with restriction

Discussion created by magar1982 on Jun 17, 2014

I want to create a path between points and measure path distance given that there is a polygon restriction. For example, I have species initial location and final location,  and big lake is in between the points. I want to create a shortest path so that it avoids lake. I guess there must be tool in ArcGIS 10x other than least cost path method that does what I want. Any tips ?

Thanks !
