The Malleo River

The Malleo is actually a big spring creek. It flows out of Lake Tromen as a very small free-stone mountain stream. Once it hits the beautiful Malleo Valley, the river starts receiving spring water from numerous tributary spring creeks including the Huaca Mamuil, the Mamuil Malal, the Tres Picos and several others.

Virtually 90% of the Malleo River water is spring water. This unique feature makes for a river with consistent water temperature and stable conditions. Hence underwater life is rich and varied, from profuse insect life (nymphs, larva, pupa, mayflies, caddis and stoneflies) to countless terrestrials and “pancora” crabs. Thus this rich aquatic life has enabled the Malleo to have one of the healthiest populations of Brown and Rainbow trout in Northern Patagonia.

The Malleo may be the truly complete river. It has diverse sections: from its scenic meadow area, with the Lanín Volcano dominating the background, to the canyon section or the lower boulder bottomed section which offers pocket water and willow-lined banks. It is just the “right size” river to fish and wade and you will always see hatches of different types – from caddis and mayflies of various kinds to stoneflies and midges. This river offers dry-fly and sight-fishing opportunities along its 20 kilometers. It offers textbook dry fly fishing in a gorgeous setting.

The Lodge

San Huberto offers a relaxing, idyllic atmosphere to enjoy with family and friends just a stone’s throw from the banks of the Malleo River. Lodging, service and amenitie are first class allowing each guest to fully enjoy the beauty of this mythical Patagonian ranch.


The fly fishing season at Estancia San Huberto is November 15th through April 31st.


Our guests will take a 2 hour flight from Buenos Aires to Chapelco Airport located just outside the small mountain city of San Martin de los Andes. Upon arrival, you will take a 45 minute transfer from Chapelco Airport to the lodge. San Huberto is ideal for combining with other fly fishing lodges in the famous Northern Patagonia Fly Fishing region such as Arroyo Verde.

Just a quick note to let you know how spectacular the trip was to Tipiliuke and San Huberto! We had success on some beautiful Browns and Rainbows. Please give my regards to my guide, Pablo—he is an excellent guide, taught me a great deal on the river, and I appreciated his patience. Lodging and service at both lodges was excellent!
