Lake Allyn no longer exists:http://homepage.mac.com/jjakucyk/Transit1/cgp/pages/page_47.html It filled in with sediment and was drained a few years ago. Says firstname.lastname@example.org
Play mini golf at Little Miami Golf Center near Lake Allyn, and a nice nearby hotel is Hampton Inn Cincinnati-Eastgate. Near Lake Allyn is a great 1.5-mile-long bit of whitewater on Backbone Creek, a class III-V, this is the Elmwood Road to East Fork of Little Miami River
sector. This bit of Backbone Creek is suggested for expert raft paddlers only. A great 1.35-mile-from-beginning-to-end whitewater part on Hershel Run is close by.
