Third week of July, I began a circuitous road trip east to Northern Virginia to see family. I stopped off at several really nice national & state parks and hiked some awesome trails, including:
Hocking Hills State Park (Logan, OH) -- Old Man's Cave Trail, Ash Cave Trail. About an hour from downtown Columbus. Really nice state park with well-marked & maintained trails. Very easy to social distance.
New River Gorge National Park & Preserve (Glen Jean, WV) -- Nuttallburg Headhouse Trail, Nuttallburg Coal Tipple, Thurmond, Sandstone. Absolutely worth the trip if you have the time. If you enjoy the outdoors, this place should be on your bucket list (but go while you can still safely hike).
Harpers Ferry National Historical Park (Harpers Ferry, WV) -- Maryland Heights Overlook Trail. Awesome views of Harpers Ferry await. Go early so you can avoid the crowds and, more importantly, get a spot to park at the train station (fee required).
Cuyahoga Valley National Park (Brecksville, OH) -- Various portions of Towpath Trail and a few waterfall trails. Located between Cleveland and Akron, so no cell phone issues. Easy access to I-80.
Indiana Dunes State Park (Chesterton, IN) -- 3 Dunes Challenge, Great Marsh Trail. IMO, the state park is better than the national park. Hiking uphill in beach sand on a hot & humid day is really exhausting, lol. Easy access to I-94 and I-80/90.
If you enjoy hiking, research the opportunities at the above parks, especially if you will be attending a road game nearby (or on the way to/from).
