Both Lake Fonck and Lake Roca are part of the Manso River Basin and share the classic features of the region’s glacial lakes: medium-sized bodies of water surrounded by lush vegetation, with limited access that helps preserve the quality of the fishery. Rainbow Trout and Brook Trout are the most common species, with Brown Trout occasionally appearing in good size. Within Nahuel Huapi National Park, these lakes offer an ideal setting to pursue them. Their geography—whether dense reed beds or forested shorelines—makes having a boat a significant advantage for anglers. Because of their remote location, farther from Bariloche than many other lakes, both usually provide better fishing opportunities. Depending on the time of year and prevailing conditions, one or the other may be prioritized to maximize the day’s success.

Lake Fonck has an elongated shape, divided into two distinct sections: the smaller Fonck Chico and the larger Fonck Grande. Fonck Chico is surrounded by thick reed beds, making fishing possible only from a boat. Fonck Grande, in contrast, offers a wide variety of shoreline structure, from extensive reeds to rocky walls and submerged vegetation, and receives the inflow of two productive streams—the Calote and the Frío.

Similarly, the Roca is bordered by dense coihue forests and abundant aquatic vegetation along its margins. It is fed by three streams—Expedicionarios, Linco, and Felipe—providing diverse structure and highly promising fishing situations.

Both lakes lie in the southwestern sector of Nahuel Huapi National Park, about 37 miles from Bariloche. In midsummer they come alive with the famous Dragonfly Hatch, one of the most thrilling times to fish here, as large trout rise aggressively to smash big, foamy terrestrials such as Fat Alberts, Chernobyl Ants, or realistic dragonfly patterns. Throughout the season, we adjust our gear and techniques to make the most of each outing.

Both lakes are located about 37 miles from Bariloche. A good part of the journey follows gravel roads, making the drive roughly an hour and a half. We typically meet between 7:00 and 8:00 AM at a designated point in Bariloche before heading to either lake to begin our day.

Once the boat and gear are ready, we fish from about 9:00–10:00 AM until 1:00 PM, when we pause for a well-deserved riverside meal. After lunch, we return to the water and continue fishing until around 4:00–5:00 PM, before heading back to your accommodation or the agreed meeting point.

 

This was an amazing fishing trip! The fishing, accommodations, and food were all incredible. I fished with these guys for three days – two floating the Manso River and one in Lago Hess. Dante was my guide and he got me on a nice mix of hefty rainbows and browns each day. First day they picked me up at my hotel in Bariloche. On the river, there were some pretty good caddis fly hatches and I fished mostly dries until the later part of the day. I lost count at 14 fish, all nice healthy fish, in the 15 inches -18 inch range. Each day lunch was done riverside with Dante firing up his portable grill and serving on a folding table. At the end of the day, we returned to a nice camp with all the comforts of home including a private tent with stand up head room and all my bags waiting. Tomas, who is also a guide, provided a well thought out camp setup and handled the cooking. Dinner time started with cocktails and appetizers followed by Argentine barbeque, salad and some nice sides. Breakfast had everything you could want from fruit and yogurt to eggs. The location of the camp made fishing the reach of the Manso we were on possible by saving us a ~2 hour drive to Bariloche each day. We launched the second day directly from the campground and fish were bigger, in the 16-20+ inch range. Not so much dry fly action and we fished more streamers. The Manso was gin clear and I was sight fishing the streamers. It was really a kick to see the monster browns turn for your streamer. The third day at Lago Hess was a “slow” day -I caught about 5 fish, all nice size browns, with three in the 4-6 pound range. Throughout Dante was on top of the leader/tippet and fly changes. Dante is a skilled fly tier and provided the all the flies for the trip. Each day had a lot of action and even the “slow” day was better that the best day in a lot of rivers I’ve fished. Our shuttle was run by Santiago who lives on the Manso. Him, Dante and Tomas are all locals that really know the river, have their finger on the pulse of current river conditions, and made sure I was on fish each day. Matias did a great job organizing everything. We discussed and he made sure I had the kind of fishing, cocktails, and meals I wanted. He also organized and provided all the gear – quality waders, reel, and rod. Super helpful if your limited on suit case capacity. Dante, Tomas, and Matias all speak good English and communication is no problem. And they’ll also help you with your Spanish if you’re learning and interested. Can’t say enough about these guys. If you’re in Bariloche and want to fish, I recommend Bariloche Fishing Trips!

We came to Bariloche hearing stories about the mystical monster trout that live in these waters. We said we would be happy if at least one of us caught one. We had our expectations exceeded with the amount of action we had. To enjoy a steak and Malbec picnic on a beautiful spot on the river made this the best day ever. Looking forward to planning my next trip down here—hopefully in the Fall to see some brown trout action!

A half day in the Limay River delivered 2 brown trout 50cm+ & 2 smaller rainbow trout in the boat and a cheaky one that I lost. Heaps of visuals from the boat with single fish swimming past or chilling on the bottom and a heap chopping in a backwater pocket that we couldn't land. Great day and well organised with Matias, an awesome guide. Thanks from this North Qld Aussie!

We had such a great day fishing with Matias' guides. My wife and I had Dante. We also had Tommy and Ali (sp). The guys were amazing, the Limay River is one of the prettiest rivers on the planet. Did I mention the shore lunch!! One of our best meals in Bariloche, and definitely the best view, wine and service.

The company arranged a wonderful trip to the Limay River. Aliosha is an excellent guide, very organized and patient. It was my first experience with fly fishing, and I was successful in catching fish (4 trouts) The best part was the beautiful scenery and the overall experience of the trip.
