Island Park Fly Shop

Open Memorial Day Weekend until October.

Open 7 Days a Week:

Summer Store Hours: 8am-7pm


Our retail staff are all dedicated anglers and know the region from years of fly fishing around Idaho and many other places around the world.  We regularly ask them to go fishing to keep up to date on the local fishing conditions.  They are also ‘hands-on’ with all the gear in our store.

Customer service is our top priority.  Whatever you need, if you have a problem, if you have a question, and even if you have a problem with something you bought from another fly shop we will do our best to make it right & get you on the water.
