The falls are located on the west side of ID 47 a.k.a The Mesa Falls Scenic Byway. From the west entrance to Yellowstone NP to the parking lot at the Upper Falls is about 50 miles. If you are coming from the south part of Idaho you will take US 20 from Idaho Springs to Ashton and then turn east on ID 47/Mesa Falls Scenic Byway. About 14 miles later the entrance will be on the left side of the road. If you are coming from West Yellowstone you will travel US 20 to Island Park and then south for about 8 miles out of Island Park to the junction with ID 47. Travel about 13 miles to the entrance to the Upper Falls.

Camping, hiking, backpacking, picnicking, and winter sports are allowed. More info and even more info.
A walkway from the parking lot/visitor center will take you to the overlook of the Upper Falls. Upper Falls is 300 feet wide and plunges 114 feet creating a thunderous roar and a far reaching spray. It is very impressive and is actually higher than the Yellowstone Upper Falls by 5 feet. The spray keeps the sides of the canyon moist which produces a small ecosystem of its own. We saw numerous species of wildflowers and birds including osprey. Eagles, deer and bear are known to frequent the area.
The only bear we saw was the rock below the falls that we thought looked like a bearThere is a mile hiking trail from the Upper Falls to the Lower Falls that takes hikers lower into the canyon and closer to the Lower Falls. It runs adjacent to the Henrys Fork River and through some trees. It is an easy hike. You can view the Lower Falls from the Grandview Campground and Overlook or from the trail. The Lower Falls plunges 85 feet creating a fantastic scene.
Lower Falls. Notice the hiking trail in the canyon.
The two falls and area are pristine. These two falls are the last two major falls in Idaho that have not be disturbed for irrigation or hydroelectric projects. The low number of visitors make this an ideal location for hikers/campers wanting some time away from the masses. The air is clean, the sound of the falls is relaxing, the surroundings are beautiful, and the neighbors are far away!

It may not be Yellowstone, but that is a good thing and it is a beautiful area. If you are in that area of Idaho I highly recommend you stop by the Mesa Falls and stay a while.
