Starting in the city of Asaph, this is an adventure that follows Straight Run Road north, climbing alongside the water. When the road ends, singletrack begins through the woods and then connects with Stinger Trail. This portion has loose rock and then a very steep plunge with technical difficulties at the end of the trail before reconnecting with Straight Run Road. This is a challenging and rewarding ride! The nearby USGS Fish Research Lab is open to the public and is worth a visit.
