Trail guide?

Has anyone here ever worked as a trail guide before? If so, what are your tips/what are some of things you love & hate about the job? Overall experience on a scale of 1-10 (10 being excellent)?

I currently work in the racing industry and would love to try and find something more low-key for the next season. My body has definitely taken a beating and I think working for a year in a slightly less stressful environment would probably do me some good, haha. 

TIA! xx
