Thousand Springs State Park
Along the Snake River near Hagerman, springs pour from the canyon walls at Thousand Springs State Park.
About 45 To 50 Minutes From Downtown Twin Falls
The name Magic Valley starts to make sense at Thousand Springs State Park, where water from the aquifer pours out of basalt cliffs along the Snake River. Idaho Parks and Recreation lists the park as 34 miles northwest of Twin Falls, and it is organized as several units that are a short drive from one another. You can hike and picnic at Malad Gorge, look into the blue water at Niagara Springs, walk historic ground at Ritter Island, or visit the Earl M. Hardy Box Canyon Springs Nature Preserve.
Box Canyon is one of the most striking units. The state park service says the springs flow at a rate of 180,000 gallons per minute, with a primitive hiking trail, a 20 foot waterfall, and a paved road to an overlook. Winter is a good time to watch for bald eagles and golden eagles. Billingsley Creek, Kelton Trail, Box Canyon, and Crystal Springs are open year round for day use from 7 a.m. to 10 p.m. Malad Gorge day use is also open year round, though the back gate is seasonal. Niagara Springs and Ritter Island have more limited seasonal access, so check the park page before you build a route.
Best Time To Visit
Late spring through early fall is the easiest time to visit several units in one outing. Winter is quieter and good for wildlife, with shorter visitor center hours.
Getting There, Fees, And Hours
The drive from downtown Twin Falls is about 45 to 50 minutes. A good first stop is the visitor center at 17970 U.S. Highway 30 in Hagerman. Hours there change with the season, so call or check the official page before you go. Idaho Parks charges a motor vehicle entry fee of $7 per vehicle per day, waived with an Idaho State Parks Passport. Pets are allowed on a six foot leash.
