Exploring Iowa is so much better on 2 wheels! This time of year is my favorite. Sun is shining Air is crisp Fall is around the corner We rode to Harmon Tunnel in Pammel State Park. This tunnel was originally only 6 feet high, 6 feet wide and 100 feet long. Dug in 1858 to get water to a near by mill. It’s so much fun exploring this state. #iowa #pammelstatepark #explore #2wheels #motorcycle...

"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!"
