Begin fishing daily after breakfast and expect to take a break in the afternoon for a siesta. After your break, you’ll get back to fishing until dark.

Fishing on the Rio Grande will lend itself to a variety of fishing styles and techniques. Brown Trout are absolutely thrilling to catch, but they are a bit temperamental. You’ll be using 7-9wt rods (12-15ft long).

December – January: During this time, sea-run brown trout begin to make their way into the river system. The fishing will be warming up around this time.

January – March: Mid-season on this adventure is peak season. During this time, you can expect the highest and best odds of catching browns.

March – April: This period features similar fishing as the early season.

Fly to Buenos Aires and then to Rio Grande airport (3-hour flight). The Kau Tapen Lodge schedules pickups for Saturdays, which is when you’ll be greeted by a lodge representative. The shuttle from the airport is approximately 1 hour.

Note that larger streamers should be weighted and should be tied on heavy hooks with good gapes.
