Crystal-clear water and a 20-foot waterfall are highlights of the 350-acre Earl M. Hardy Box Canyon Springs Nature Preserve near Twin Falls, site of the 11th largest spring in North America.
Here 180,000 gallons of water per minute pour into the Snake River. Still in development as a state park, it is co-managed by The Nature Conservancy and the State of Idaho. Access is limited for the near future. Contact Malad Gorge State Park if you are interested in visiting the area. Some of the activities in this area include hiking, fishing, and biking.
