The trail starts behind the floodwall. You can park in the lot on the other side of the wall at the end of Byrd St. close to the Manchester Bridge and 10th St.
Someone told me it’s a sewer pipe which seems kind of ironic because it’s so nice. You can walk on this metal grid over the pipe a long way over rapids and rocks. There’s a few easy places to climb down to walk on a sandy beach downstream from the rapids. Farther upstream you can go out on the big rocks. The trail goes over part of the pipe without the walkway then through the woods next to the river and up to the end of Browns Island.
It’s a wild beauty in the heart of Richmond.
