[R] Minumum descent path between to peaks

In a xyz-loess fit to a set of data data, I have two
distinct peaks with a saddle in between, but the
slopes of the two peaks are not colinear.

I have to find the path I would walk to get from one peak
to the other over the saddle to construct a profile for

Can anybody give me a hint? I can start with two line
segments peak-saddle-peak and use optimization,
but what exactly should be minimized for this task?
