Thank you to all for the information, however my original question remains:
Due to a fear of heights I've already eliminated any possibility of taking the Napoleon Route out of SJPP. Does anyone know if there are there any areas of the Valcarlos Route with a trail and side that drops off the mountain as does a section on the Napoleon Route?
This phobia of mine, like most phobias is not rational. It is the fear of perceived danger, not the actual danger that is troublesome. I seek this information because if there are areas like this on the Valcarlos Route I will not begin the Camino in SJPP, but rather at another place.
As for heights and drop offs along other areas of the Camino - that is a different issue, I am soley concered now about the Valcarlos route from SJPP.
Thank you so much to anyone who might be able to answer with specific information on the Valcarlos Route.
Thank you again to those who took the time to post responses. As for wolves and vultures - bring them on - no fear of those things!
