According to the Hocking Hills visitors center, summertime in Ohio brings temperatures that are nearly always comfortable, ranging from 50° to 85° F, with cooler temperatures in the evening, in the caves and gorges and on the shaded trails. Try dressing in layers, as the Hocking Hills weather forecast varies throughout the year and temperatures can fluctuate often. Good, sturdy hiking boots or athletic shoes are important on the trails.  Afternoon rain showers are not uncommon this time of year.

For BAGSFOW you may want/need to bring:

swimsuit, sunglasses, hat
luau clothes
light rain jacket – especially those going to see Tecumseh
hiking attire

yoga clothes

wedding attire – take a tip from the Pip, dresses are always in style (silly hats too I guess)… whatever you are comfortable in

Super fun clothes you will want to be photographed in… you never know where the paparazzi will show up!
