Three Rivers Ranch & TRR Outfitters:

Three Rivers Ranch would like to welcome you to TRR Outfitters, our full-service online fly shop! This fourth generation family owned and operated business has been providing anglers with superior lodging, guided fishing trips in Idaho and Montana, top quality gear, education and resources for over 90 years.

Three Rivers Ranch is a world class fly fishing destination nestled in Warm River, in the south eastern corner of Idaho. The history of Three Rivers is what makes it such a unique place for any angler to get away and experience what fishing in the west is all about.

Lonnie Allen has been the owner and operator of Three Rivers Ranch since 1987. Lonnie’s grandparents Fred and Berta Lewies homesteaded and started the Warm River Inn and Rendezvous Dance Hall in Warm River in the 1920's. The business grew into a small resort area with a café, dance hall, cabins and train stop for tourists headed to Yellowstone National Park. In 1974, Lonnie's parents, Harry and Lillian Lewies approached The Orvis Company about opening one of the first Orvis endorsed fly fishing lodges. In order to receive such an honor, a lodge must meet the rigorous standards that Orvis expects from a fly fishing lodge. Through Lonnie’s care, Three Rivers Ranch has grown into what Andrew Harper’s Hideaway Report calls one of the Ten Best Classic Fishing Lodges in the World and was named Orvis Lodge of the Year.

The exceptionally high standards that Three Rivers Ranch upholds assures you will find great service, great fishing, the most professional guides and staff, and a knowledge for the industry you won’t find anywhere else.

In 2001, Lonnie took her love and enthusiasm for fly fishing to new heights by adding two more full service fly shops in Island Park and Driggs, Idaho. While Three Rivers Ranch continues to provide outstanding service to anglers through our lodge and retail stores, the Internet has provided us the opportunity to offer this same award winning service to anglers all over the world.

Whether you’re looking for a week long fly-fishing getaway, a day trip on blue ribbon waters through one of our full service fly shops or looking for the most dependable brands and gear, Three Rivers Ranch and TRR Outfitters can take you there.
