10 Fishing Holes in Southwest Idaho

All you can hear is the sound of the river, the wind and the birds as you cast a line into the clear water.

You watch the steelheads glimmer under the surface, breathe in the mountain air…and wait. It’s peaceful and quiet, the kind of place that anglers dream of and locals keep a secret.

These are the fishing holes that bring fishermen from all over the US to Southwest Idaho. The region is home to thousands of miles of reservoirs, rivers and lakes — and it’s one of the only places this far inland where you can catch steelhead trout and salmon.

Ready to kick off the fishing season here? We’ve got 10 fishing holes no one should pass up.
