N16 59.352 W88 24.013 The turn off to Davis Falls Preserve is in the village of Alta Vista alone the Hummingbird Highway. I have no first hand experience with the preserve and online info is sparse. The falls are located about 12 miles from the highway and the last two miles are done on foot. The falls are reputed to be about 500 feet high and end in a spectacular pool. It is reachable with a guide only but it sounds like it could be a very good birding location.
