It was totally amazing, definitely recommend for you to do it. Well it was kinda moderate hike and some part was high, i would recommend to do some hiking trainning before hand, however the tour provided you with 2 poles so they help with your balance. Make sure you prepare for extra 2-3 kms once coming down to get to your car park i know when your legs were tired and relaxed and have to do a couple extra kms could be tiring. Bring some extra yummy food from home because the food they provided were not sufficient.
The group was small only 5 the guide John. He was a great guide very attentive, cheerful and caring. He kept checking our pace and how we were travelling, gave us some tips and suggestions, he was very knowleagable about the granite and mountains and told us about the how the mountains formed the way they are now. Absolutely Otra Vez!
