From Sioux Falls, SD it was maybe a little over an hour drive to Hawkeye Point – the highest point in Iowa. We set out early because the weather predicted storms and we were hoping to catch a tiny window before the rain. Actually we ended up driving through the rain and got ahead of the storm as we reached the highpoint.
I plugged in 5467 130th St Sibley, IA into the GPS which is the address I found on roadsideamerica.com and it took us right there. It was very easy to get to and since everything is so flat we could see the silo and flags in the distance (as well as the approaching rain) as we drove closer. For some reason my GPS took us off the main road and down some dirt roads the back way to the entrance, but either way works.
