The Swan River is a small tributary of the Blue River that starts up by Breckenridge and makes its way down into Dillion Reservoir. Along the way there are many wary brook trout available for the hunting and with it so close to a bunch of other good fishing rivers and creeks, sees less pressure. Much of the water is public and easily accessible if you can hike along a river. The stream is a gorgeous little gem and for people looking for some solitude close by or to chase some small and tricky brook trout, this place will test your skills and provide a fun day on the water.
