Completing the trek is just an amazing experience but also it is challenging. Honestly, without the help and support of our guide, Ramiro, my wife and I could not have completed it. His personal attention to our needs made a big difference to have this experience the best.
Several items of my bucket list completed: jump into a glacial cold lake at 15000 ft, sleep out with stars on my roof as never seen before, and canope holding my wife's hand ! Thanks for the great experience !!
Small note of caution: prepare yourself, it is a lot of fun but it is a really tough ride that requires your best mentally and physically. We thought it would be difficult but doable with regular preparation we suffered to keep the pace.
