Tucked into the forested foothills just east of Afton lies one of nature’s quiet curiosities—Periodic Spring, also known as Intermittent Spring. Unlike most springs that flow steadily year-round, this rare geological phenomenon has a rhythm all its own. The water surges from the mountainside for several minutes, then mysteriously slows to a stop—only to begin again in a repeating cycle.
Scientists believe this unusual behavior is caused by a natural underground siphon system, where water builds up and releases in intervals, much like a hidden plumbing mechanism beneath the earth. While there are only a handful of springs like this in the world, Periodic Spring is thought to be the largest of its kind, making it a uniquely fascinating stop for curious travelers.
Reaching the spring is part of the experience. A pleasant one-mile hike leads you into a narrow, steep-sided canyon where the sound of rushing water echoes off the rock walls. The trail follows a lively mountain stream, weaving past clear pools and small cascading falls that add to the sense of discovery along the way. The scenery feels tucked away and peaceful, offering a refreshing escape into nature.
While the on-and-off flow of the spring is subtle rather than dramatic, there’s something quietly mesmerizing about standing beside it, waiting for the moment it returns to life. Combined with the beauty of the canyon and the gentle hike to get there, Periodic Spring is less about spectacle and more about experiencing one of Wyoming’s most unusual and serene natural wonders.
