"Very cool surroundings around the bridge. Love the stone around it; and coming this time of year with the colored leaves- beautiful. Was looking it at as a possible filming location 🎥"

"This tunnel is pretty cool. It's in the state park called Pammel which is just south of Winterset a few miles. The whole park is worth the trip! There's a ford you can drive through if it's not too deep. I took the kiddos to do this yesterday and they really liked it. You can also easily enter the water to kayak or float. We highly recommend this park!"
