Absolutely amazing experience! I went here with my dad and we had a great time. Our guide Kerry was incredibly knowledgeable and taught me things I had never learned in my years of fly fishing. The staff on site were so impressive, they knew guests by name and were willing to do anything to make your stay great. The food was out of this world and the accommodations were clean and comfy! I hope to return here in the future. Lonnie has done a great job with this place!

We fished with Izik for 2 days! He is an absolute professional in every way. He knew every inch of both rivers we fished. He taught my son and me so much and he had amazing patience with us. Can’t thank him enough for a fantastic time on Idaho’s amazing trout rivers.
