The Eagle River is a popular fly fishing destination located in the state of Colorado. It is known for its abundant population of rainbow and brown trout, as well as its scenic beauty and easy access from the town of Vail. The river is a freestone stream, meaning that it is fed by snowmelt and has a clear, cold water flow. It is a relatively small river, but it is well-suited to fly fishing and offers a variety of fishing conditions and opportunities for anglers of all skill levels.

Can be challenging due to its popularity and ease of access.

Mostly frozen.
In most parts, it's fully wadable. High-water months (Spring / Early Summer) can be tricky.
