Ohio’s northern reaches are flat and somewhat uninspiring. But southwestern Ohio is packed with unexpected hills and wildlife-rich rivers. Set up camp in Yellow Springs, an artist and hippie hangout an hour from Cincinnati, at the Glen House Inn, next to a thousand-acre nature preserve. The town is deservedly known for its local art shops and the 75-mile Little Miami bike trail, which stretches almost to Cincy. But its best features are the nearby limestone gorges in John Bryan and Caesar Creek State Parks, which offer some of Ohio’s best hiking.
