Get your family's hiking boots ready! It's soon to be autumn in Tennessee and that means the possibility for lovely, crisp days outside, instead of sweltering hot ones. Owl's Hill, Brentwood's beloved local nature sanctuary located at 545 Beech Road, offers up three FREE HIKE DAYS on Saturday, September 10; Saturday, Oct. 1; and Saturday, Nov. 12. An Owl's Hill staff member or volunteer(s) will guide your gang through Owl's Hill for an approximate two- to three-mile hike of moderate hill climbing. Hikes start at 1 p.m.; last hike leaves at 1:30 p.m. Clear a Saturday and register your family now!
