Marvel at Big Springs' crystal clear water on your way to Johnny Sack's historic log cabin. 

Big Springs is the headwaters of the Henry's Fork of the Snake River. Producing 120 million gallons of water per day, the spring forms wide and crystal-clear pools filled with trout (no fishing allowed). A paved trail leads to historic Johnny Sack's cabin, which is open for tours during the summer.

Park in the paved lot to the north of the wooden bridge. Walk back across the bridge while looking for large trout swimming in the shadows. Seagulls abound, on the lookout for snacks from tourists. 

Take a detour and walk down either side of the river for great views. 

From the bridge, continue south and follow the signs for Johnny Sack's Cabin (open in the summer from 10:00 to 4:00). Keep an eye out for waterfowl and minx.

Camping is available nearby at the Forest Service's Big Springs Campground.

Driving through the area on our way to Montana, we had picked up some sandwiches a couple miles back and decided to stop for lunch. When first arriving we could not believe how clear the water was! The bridge was perfect for pictures and the cabin was so cute. Although there were quite a few people and seagulls around, we were able to find a nice quite and shaded area to eat. It was the perfect pit stop! 10/10 recommend!

You can drive here and see the springs and cabin without walking. There are coin operated machines to buy food to feed the huge trout under the bridge. Really pretty place. You can choose to hike along the river or just stay close by the parking lot. The walk along the river is easy and well maintained.
