Cedar Bluff Lake – SW of Hays, Trego County – With advance planning, group rides are allowed by special permit. Many sites to see in and around Cedar Bluff area. Just north and west of Bluffton area within wildlife area, lies Threshing Machine Canyon. Canyon was a station site for the historical Butterfield Overland Trail during the mid-1800’s. For many years, the remains of the old threshing machine could be seen. To this day, names and dates of many travelers from this era are still engraved into limestone bluffs and boulders surrounding the area. (Area is a wildlife refuge and is closed from Sept 1-Mar 10.) Just west of Page Creek Area are cedar lined, 100-ft limestone bluffs, from which reservoir’s name was derived. Area provides excellent hiking and stunning views of reservoir surrounding mixed grass prairie and rolling hills of Smoky Hill River Valley. Contact park manager at 785-726-3212.
