Ys or Mayfield

I was gonna do ys but mayfield sounds better to me

Yup, loved Mayfield! I'm not athletic or terribly coordinated and not in great shape. The guide held my hand to steady me in certain places. The hardest part was the climb up the hill to the road at the end.
Private guides do work for tips only and were great. I would plan on at least $20 as they're with you for a couple of hours.
It is beautiful, refreshing, natural and the lunch they serve is awesome!

I am an overweight guy with heart problems and brought 6 and 9 year old kids with me and although a few hills were slow going we had no problems and would do it again in a heart beat.

We've done both and would recommend Mayfield for sure. And yes, they work for tips and they expect big tips too!
