Every state is full of hiking trails that are worth exploring. I've explored many in PA, OH, WV...the list goes on! So, I thought I'd just share some links to parks you might want to check out in Ohio. I didn't provide much on each trail but if you follow the links you'll be able to find out more details than just the location if it seems like the right trail for you!
You can often spot eagles here! Located in Northwest Ohio.
Located in Munson, OH, this preserve is 101 acres large. It has scenic lakes and lots of places to spot water fowl as well.
