Along the scenic South Fork of the Snake River, the 1-mile Cress Creek Nature Trail interprets life in the area as it is now and as it was long ago. The trail climbs through sagebrush-grass communities, over juniper-covered slopes, and along a lush perennial creek. The watercress plant, a favorite food of moose, gives the creek its name. If you hike quietly you may see deer, rabbits, small lizards, or possibly an eagle or a moose. When skies are clear, prepare for an expansive view of the Snake River, volcanoes and surrounding farmland.

The nature trail is self-guided, with interpretive signs along the way. The first 1 mile is wheelchair-accessible.

About 20 miles northeast of Idaho Falls, Idaho. From Idaho Falls, take the North Yellowstone Highway north through town. Follow Highway 26 northeast towards Ririe and Jackson. About 3 miles past the Ririe turnoff, follow the signs to Heise. Bear right after crossing a large irrigation canal. Cross the Snake River and turn left immediately onto the gravel road headed towards Rexburg. After 1 mile, the trailhead parking area is on the right side of the road.
