Fort Howard Dungeons are open every Friday and Saturday night in October. We start letting tours into the park at 6:30PM (Tours don't begin walking until it is dark. The gates will usually close by 10 to 11 PM Depending on capacity or how many people are still in the venue. If there is pending inclement weather as in rain or storms, we will post on Facebook if we are closing for the night. We will make every effort to make sure the rides are open for your entertainment.
