Prior to our trip, we will meet up for a briefing session in order to go over details of the trip and equipment check

Once we're all set, we'll transfer towards the bridge in Río Eléctrico where we will begin with a two-hour trek to the Piedra del Fraile refuge. Then, we will continue with a more demanding trekking trip where we'll traverse through 800 m of uneven terrain for aproximately 3 hours until we reach the Piedra Negra base camp.

Day 2: Guillaumet

We'll rise early and head to Paso Guillaumet until we arrive at the base of the Amy route. The first 200 m stretch will take us to the ridge of the mountain. After four trails with grade 5 difficulty, we will reach the summit ridge. After a 15-minute walk, we'll reach the long-awaited summit. The descent will be realized through the same route.

Depending on the conditions of the route and the weather, the alternative route would be Fongrouge.

I was looking for a local guide for a hike I was planning and came across Explore-Share. They seemed to have good reviews and so decided to give them a try. The experience was very positive and completely happy with their service. I will be using them again for next trip.

Thank you explore-share for a wonderful via feratta experience. We have been wanting to learn for a long time but don't have the facilities in Scotland. The guide Mitja was extremely helpful and knowledgeable, answering all my many questions and providing advice. On the day head to take another group but he quickly arranged another guide Borut, who was brilliant. We had a fantastic morning learning via ferrata at Hvadnik in the gorge. It gave us the confidence to later hire our own equipment and go out in Mojstrana. Altogether a five star + experience. Thank you.

Hello! I have been thoroughly impressed by the service and assistance that explore-share have provided the past couple years in helping to plan my trip to the High Tatras in Poland. I really appreciated the flexibility that they provided in allowing me to rearrange my trip twice owing to covid. They were responsive and communicative throughout. This trip was part of my Stag weekend celebrations and explore-share connected me with an outstanding guide in the form of Marcel - he was an excellent recommendation and we really enjoyed our guided hike in the High Tatras with him. Marcel was an outstanding professional, placed a high focus on preparing well and staying safe, and was also a great guy! Highly recommend. Many thanks and best wishes - Richard
