The notable sites in Star Valley Ranch, WY, range from a world-record natural phenomenon to historic landmarks, championship golf, and some of the darkest night skies in the region.

The Intermittent Spring
Just east of Afton, tucked into Swift Creek Canyon within the Bridger-Teton National Forest, sits one of the most unusual natural features in North America. The Intermittent Spring is the largest rhythmic spring in the world and one of only a handful of its kind known to exist anywhere on earth.
What makes it remarkable is its behavior: from late August through May, the spring cycles on and off at regular intervals, flowing for approximately 18 minutes at up to 100 cubic feet per second, then stopping completely for about 15 minutes before starting again.
What to Know Before You Visit

The World's Largest Elkhorn Arch
At the intersection of 4th and 5th Avenue along Highway 89 in downtown Afton stands the World's Largest Elkhorn Arch. Spanning 75 feet across all four lanes of the highway at 18 feet tall and constructed from over 3,000 elk antlers, it is one of the most photographed landmarks in Wyoming.
The arch was built in 1958 by the Afton Chamber of Commerce using antlers obtained through the Wyoming Game and Fish Commission. It has been maintained and added to since completion and requires an annual coating of a special plastic finish to preserve the antlers.

Golf and the "Tunnel Hole"
Star Valley Ranch has built a reputation as one of Wyoming's top golf destinations, and the courses operated through the Star Valley Ranch Association are central to that reputation. Cedar Creek is an 18-hole, 6,553-yard course that winds through the community's natural terrain, featuring meadows, tree lines, and mountain views.
Aspen Hills is a nine-hole course set higher on the property among aspen groves, known statewide for its difficulty.
