==General Description==

A wonderful trek through the valley of the Aviles River which connects Jeinemeni National Reserve with Estancia Chacabuco, a national park in the making. The trail follows a route the first colonists in the area used to travel between Cochrane and Chile Chico. While this description is from north to south, it is also possible to do this route in reverse.

==Route description==

===Day One===

*'''Administration - Refugio Valle Hermoso'''

===Day Two===

In this stretch you will have to cross many small streams. It is very important to have a pair of sneakers or sports sandals that can get wet or you will waste time taking off and putting on your hiking boots. This author recommends a good pair of Crocs. As a general rule, always look for where rivers divide into many shallow streams to find a safe place to cross. Follow the cairns and red poles towards the end of the valley. The path is always clear, but depending on the water level, it's possible you will have to leave the path in search of a safe crossing.

The climb to the pass is very gradual and you'll reach the top an hour after entering the forest. Here you have a beautiful view of the Aviles river to the south and the glaciers of Valle Hermoso behind you. You are now entering the private property of Estancia Chacabuco. The descent to Puesto Limite, a campground at the end of the Estancia's property, is very fast. Here you'll find a palisade to protect your tent from the wind, a fire pit, and benches.

===Day Three===

Now in the property of the Estancia, the trail is very well marked. There are many sites apt for camping which can facilitate two shorter days if your party is tired. Follow the trail to the south. 45 minutes or an hour after Puesto Limite you'll reach another campsite. Take water from the river itself. A few minutes on the trail fords the Aviles River. The trail enters the forest again and starts a long, gradual descent. Two kilometers after crossing the Aviles River, there is a deep tributary that also must be forded. Take comfort in the fact that this is the last time you'll have to take off your shoes. The south side of this tributary also offers a good spot to camp.

Between 3 and 5 days. A fit, determined hiker could do it in 2 days, but this itinerary wouldn't allow much time to enjoy the splendor of the Upper Aviles. Due to the number of excellent campsites, a more relaxed group could take 4 or even 5 days.

Jeinimeni National Reserve has an entrance fee of 1.000 CLP for Chileans and 2.000 for foreigners. Camping is free anywhere in the Reserve, except at the entrance where the site costs 10.000 CLP.

Access to the Estancia Chacabuco is free. As of summer 2014, Stone House Campground is also free. West Winds, the campground near the administration which provides all necessary services, costs 5.000 CLP.
