Although rerouted in recent history, the Black Rock Trail is one of the oldest mtb trails in Central Oregon. The name of the trail is derived from the route around a massive bed of dark lava rock. The trail starts on the East end at the Lava Lands Visitor Center.
Recently a paved path was placed parallel to the Black Rock Trail which allows for families and riders of all skill levels a chance to ride and explore the area. Start out on the paved path, and within 50 feet there is a singletrack trail on your right. The trail is mostly green with sections of technical lava rock. You can bail at a few places along the way to head back over to the paved path if need be (it’s about 50 yards away).
About half way down the trail there is a fork to the right which takes you up onto the lava field. It’s a great viewpoint for the Cascade Range and you are literally surrounded by miles of lava. The trail extends up over the lava field to the South and winds through some trees for about 1/4 mile when it dead ends.
Past the turnoff to the lava field, the trail meanders down to the Railroad tracks, and eventually kicks you out on the road near the Benham Falls parking area and pedestrian bridge. You can connect to the Deschutes River Trail here or head South to Sunriver.
