During these last years trekking through natural trails has become the most popular sport and the one that has more fans among the different adventure sports. A backpack, a sleeping bag, good quality warm clothes and a few more things is all you need to go hiking the trails and paths in this National Park. Advice on the difficulty of the route is important, as well as finding out about the weather conditions before you leave and including an experienced member in the group as a guide. For more complicated treks, whether they are on ice or to very high places it is always better to hire a mountain guide. There are innumerable trekking trails in this National Park, in general it is convinient to spend the night at one of Club Andino´s mountain shelters. Supplies are always available at these shelters and also spending the night in a very special place are a good idea.

Lake Gutierrez- Frey shelter:
The hike starts at the camping site by Lake Gutierrez, located at the end of a gravel road that joins it with Los Cohihues Village. There is a fairly long horse trail from the camping site. It is important to pay attention to the forks on the path. The trail separates from the lake and joins the old cart road from Catedral Ski centre, as we follow it, leaving the lake to the left we will find a sign which says " Picada Eslovena", which is in a glade in the woods ( the former cart road got to this place). The trail climbs until it meets the path to Catedral Village ( if you are comming down you will see two signs which indicate the paths to Lake Gutierrrez and Catedral Village). The average walking time is 5 hours.

Frey shelter - Rucaco Valley- Jacob Shelter Trek:
This is one of the most common treks in the area, it connects two Club Andino shelters. It goes along Catedral´s highest peaks and along very steep slopes, therefore you must be very careful and seek advice at Frey shelter.

As you leave Frey shelter, follow the path along Toncek Lagoon, and climb up to Schmoll Lagoon and the "football pitch", the Rucaco Valley starts here. It is worth mentioning that the path is clearly signalled and it is difficult to get lost.Once in the valley, the trail goes into the woods. Vast marshes are crossed in this valley and as we head towards the wide slope from Mount Brecha Negra we will walk away from the stream on our right. We will climb the northern ridge of this mountain, and once we get to the pass we will see Jacob shelter.We will continue along a steep scree, going down towards the centre of the marsh, to the north of Jacob Lagoon. Then we will come upon a dry stream which crosses a fringe of Ñires ( native bush, similar to the beech tree) and allows us to reach the shelter through a trail in a few minutes. The total length of this trek is approximately 6 hours.

Jacob Lagoon- Black Lagoon:
This trek is more complicated than the others, it requires certain climbing skills and the use of ropes or equipment for ice may be necessary. The company of a mountain guide is advisable, which can be hired at Jacob shelter.

From the shelter we head towards Los Tempanos Lagoon (icebergs) and from there, we start climbing the northern slope which takes us to the ridge behind Pico Refugio. It is very important to study the route before starting to climb. This is the most difficult part of the journey, it is quite dangerous and requires some climbing skills.The main path goes along the middle of the "wall", and it is possible to trek along the sides. As we reach the ridge we will have a beautiful view of the area. The direction is south-north and we get there through a pass between two small rock towers.The trail continues across large screes, along the top of Mount Innocentes. As we reach this second slope we will have to come down a few metres towards Navidad Lagoon so as to reach later the depression which precedes Mount Navidad. After reaching the top, we have to walk 500 mts. along the ridge and we will get to the beginning of the canyon which will take us to Vivac Rock, on the edge of the trail to Black Lagoon, as we follow it we will get to Manfredo Segré shelter. This trip is approximately 5 or 6 hours.

Black Lagoon ( C.A.B Lagoon - Blue Lagoon)- Lake Mascardi:
This is a two day journey through areas where there are very few trails. As we leave the Black Lagoon shelter, we walk along the northern shore of the lagoon and climb to the depression located to the north of Mount Negro. From the depression we must walk very gently towards the upper part of the valley, to an tributary of Lluvuco Stream, which we have to follow until we reach the valley´s main stream. After crossing the stream we start a steep climb, through colihue canes (bamboo canes) and a wood until we get to C.A.B. Lagoon. We have to walk about 100 mts. along the shore covered with "Ñires", and then turn upwards, trying to reach the screes which are higher up with the help of some dry stream. From the ridge, we climb Mount C.A.B. and then we come down again to the " Mallin de las Vueltas" (a marsh). This can be a good camping site. The length of this journey is 10 hours.

The second day we leave from the marsh and we climb straight ahead towards a diversion which comes from Mount Bonete. Once we have reached the main ridge, we come down along the opposite slope towards Cretton Lagoon´s drain. From the back of the Cretton Lagoon, along a gentle slope, we will reach the ridge which surrounds the Blue Lagoon to the East. From here, we have to come down the slope towards the lagoon´s drain. We have to descend through the valley, always to the left of the Blue Stream, along the trail which goes towards the River Manso, which is crossed at the hanging bridge, about 2 kms. before the river mouth. The length of the journey is 8 hours.
