Island Road is a 1.5 mile loop trail located near Belpre, OH. The trail is good for all skill levels and primarily used for hiking.
The trail isn't actually in Belpre OH, it is on Blennerhasset Island in the middle of the Ohio River, just offshore of Belpre OH and Parkersburg WV. You reach it via personal watercraft or ferry from Parkersburg WV.
Good trail though, not too difficult even for someone with breathing issues like me.
