The history and hospitality of Three Rivers Ranch is what makes it such a unique place to stay. Lonnie Allen has been owner and operator of Three Rivers Ranch since 1987. Her great-grandparents, Fred and Berta Lewies homesteaded and started the Warm River Inn and Rendezvous Dance Hall in Warm River in the early 1920’s. The business grew into a small resort area 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 reach rigorous standards that Orvis expects from a fly fishing lodge.  

After 30 years, Lonnie is excited to celebrate this momentous anniversary of her operations at Three Rivers Ranch this summer. Now a four generation family business with all 4 of Lonnie’s children having some involvement in the business. In addition to her celebration, Three Rivers Ranch will be offering 101 fly fishing lessons all summer for free!
