The Provo River is Fish Heads Fly Shop specialty, although they also offer guide trips on the Green River in Wyoming and the Uintas' Strawberry River as well. The Provo River is an excellent trout river, one of the best in the Rocky Mountains. And as it's not as well known as the Green, the fish are especially plentiful. Most of these trips are full day, although half day trips on the Provo are available.
Price dependent on length of trip, river and group size.
