If you are interested in fishing, you can visit the rivers and lakes in Lanín National Park, where you can practice the following modalities:

* SPINNING

This modality consists in casting artificial lures from the coast, by means of a fishing line. In the lakes it is advisable to try your luck from shores with moving water or surfs, which maintain a lot of oxygenation, benefiting the activity of fish in search of food, in general in mid-depth areas.
To choose shores where to start, look for bays, rushes, streams mouths, sunken trees or big stepping stones. agua.

Recommended equipment:  
Rods from 1,80mts. to1.95mts.  
Spinning Reel able to load 150mts of 0,30mm nylon.  
The recommended lures for this modality are 30-40 grams spinning spoons of varied colors.  

* TROLLING

This modality consists in dragging an artificial lure from a craft with any kind of propulsion, by means of a conventional or fast-sinking line. 
 
The advisable equipment comprises:  
Heavier rods that those for spinning.  
The reel, either trolling or spinning, which is used with fast-sinking lines.  
The lures for this modality are: spinner-type spoons, rapala-like fish, caiman, flies, jigs, etc.  
 
This fishing modality can be done near the surface, in mid-depth water, or in depth; in each case, the appropriate equipment and lures should be used. In the event of not having your own craft, you must hire a professional fishing guide entitled by Lanín National Park.  

* FLY CASTING

It is the technique that is capturing more and more followers, and it is the one that offers the most opportunities to fish, which gives this modality more sport character. This technique consists in casting a lure called fly by means of a line of variable diameter commonly known by the name “running line”. At the front section, a tract of nylon called “leader” of about 3 mts. will be tied from the thickest to the thinnest. The thinnest part is called “tippet” where we will tie the fly.  
There are several types of running lines, we recommend you to have at least two types, a floating line and a sinking one.  
 
The equipment to be used in our Patagonian lakes and rivers includes  fishing rods for  weight lines  Nº 6 or 8, and reels with two spools: One with a sinking line and the other  with a floating line , which will allow you to practice with flies that float on the surface of the water, imitating small insects that naturally alight on it.  
There are three fundamental factors to keep in mind; location of the trout, the selection of the appropriate fly and the presentation of it, which will be fundamental for attracting trout.
