The Collón Curá is one of the largest rivers in the area, and offers a variety of fishing depending on the time of the season. It is well known for the minnow run in February, as well as the willow worm hatch and the abundance of pancora crabs, making it a fabulous environment for trout to live. There are also interesting mayfly hatches. Early in the season, streamer fishing can be very productive. With many different channels, riffles, deep pools and cut banks, the Collón Curá is highly populated with both rainbows and browns.
