you can use Find Shortest Path SOP and make it prioritize convex curvature areas 

since it's a bit ambiguous where should the ridges start and end you will need to provide a hint like start and end positions

here is an example of specifying start and end positions using simple curves and it will try to find the best path following ridges, if it doesn't you can always define long paths by multiple shorter ones
