Mesa Falls Scenic Byway

"Mesa Falls is fabulous. It's the largest waterfall on the upper Snake River, it's a destination. It's become more and more popular as time goes by. It's an awesome and powerful sight because you can get up right next to it. You get down on the walkways and you are right on the brink. I think that just amazes everybody."
        --Sue McKenna-Ashton-Island Park Ranger District

From Ashton, Idaho, the Mesa Falls Scenic Byway heads northeast into the lush landscape of the Targhee National Forest. It's a loop that runs for nearly thirty impressive miles all the way to the Island Park area.

This byway includes the popular Warm River campground and two of the most spectacular waterfalls in the West — lower and upper Mesa Falls. At the upper falls you can stop at the historic Big Falls interpretive center to learn about the geology and history of the area.

In the winter visitors can travel the byway by snowmobile to get an entirely different type of experience. Near the northern end of the byway Harriman State Park is an 11,000-acre wildlife refuge where you can enjoy hiking trails, horseback rides or fly-fishing on the world-famous Henry's Fork.
