Great Bear Valley Trail is a heavily forested trail with easy access and free parking.
Great Bear Ski Valley is a ski area in Sioux Falls that also has wooded trails that run throughout the property. The trails are free to hike and offer a secluded, private place to get outside and away from the city.
In the winter, the trails can be used to cross country ski as well. We found this place this summer and consider it a gem of Sioux Falls. There is no traffic noise, hardly any other people there, and free to hike at. Our kids love exploring the trails and finding all the little critters. Speaking of critters, there are definitely bugs, so bring bug spray!
