Yes, you are right.....there is a lot involved in Mayfield, though a great trip
But if anyone has problems walking or with their back, I would definitely recommend YS and Black Safari.
You can be as active or as relaxed as you want to be, and still get the same great experience.
YS does not involve any hiking at all if you dont want it to.
And I love YS, it is beautiful! Absolutely breathtaking....you will be very happy with your choice.
