The Seneca Ridge Trail is a fun trail with plenty of good climbs and descents. You will begin at a historic site, Black Rock Mill, and ride alongside the Seneca Creek. There are several easy creek crossings that are easy to splash through or ride across on a bridge. The trail is great singletrack with beautiful scenery, great views, and parallels the Seneca Creek. The trail does not contain many technical features but the ups and down, long climbs, creek crossings, and switchbacks make it a very fun trail to ride. It is possible to do a one-way ride but the parking on the Riffle Ford Road is limited to about four cars and is a quarter mile north of the trailhead.
