Upstream is a bouldering area in Cuyahoga Valley National Park in Ohio, managed by the National Park Service. It sits among a cluster of climbing and hiking spots, with Chippewa Creek and Midstream both about 0.2 miles away and the Hemlock Trail just 0.1 mile off. The area is a bouldering destination, with 14 routes listed, all of them boulders. The grades run from V0 to V9+, with the median around V3.
