Stone State Park, Sioux City
(4.4/5 based on 55+ reviews on the web)
Stone State Park is a state park of Iowa, USA, located in the bluffs and ravines adjacent to the Big Sioux River. The park consists of 1069acre in Woodbury and Plymouth Counties near Sioux City, and overlooks the South Dakota-Iowa border. Stone Park is near the northernmost extent of the Loess Hills, and is at the transition from clay bluffs and prairie to sedimentary rock hills and bur oak forest along the Iowa side of the Big Sioux River. A variety of prairie plants can be found on the steep slopes and ridges, including yucca, penstemon, rough blazing star, silky aster, and pasque flower. Wild turkey, white-tailed deer, coyote, and red fox are found in the park. Birdlife includes the turkey vulture, barred owl, rufous-sided (eastern) towhee, and the ovenbird. Exposed bedrock in the park is composed of lignite, shale, sandstone, and limestone, and dates to the Cretaceous period; it is rich in marine fossils. The park contains many miles of hiking and equestrian trails, and is a popular destination for day visitors, overnight campers, mountain bike enthusiasts, and picnickers.

  • It has trees and trails and a pond. There are even lodges you can rent. I like to go mountain biking. The ranger does a very bad job and should be fired!

  • Perfect spot to take the kiddos on a little adventure. Go down by Turtle Lake and walk the horse trails...they are wider allowing for a little bit better hike with little one and strollers. Get 'em out there before they shut down for the season! Plus, you'll probably see some deer as this place is loaded with them!
  • Normal bass and blue gills and catfish on the bottom. No walleye, northern, musky, trout? State park?
  • Large, hilly, well forested park. Many trails, but views aren't great, and while many trails are very well marked, other tracks are not. Cell reception disappears soon after entering the park, so make sure to download or pick up a map.
  • Nice cabins to rent and beautiful wooded trails with occasional vantage points of sioux city.
  • This park is absolutely fantastic! Incredibly beautiful trails and so many them to hike! The only catch is that their bathrooms (for a state park) leave something to be desired... Fairly gross overall, not the worst ever, but they could be definitely better maintained. Otherwise if you like state parks and camping with lots of beautiful forest area and trails this is a must stay.
