Latest add to Deer Valley is this fast downhill flow trail. Super fun, well built and well designed trail.

The trail is very accessible, so quicker riders should expect to catch up to slower traffic and some of the big, fast, descending berms seem to be catching out less experienced riders, so keep a lookout for riders down in those areas.

      So you guys know, DV is re-doing this trail to make it a black not a blue. Faster flow, bigger jumps.

      Bomber flow trail for all abilities. Great warm up run, watch for slower riders around sharp turns.

      Super fun, well built and well designed trail. Everyone who hit it this weekend was grinning ear to ear. I would also have liked to see some jumps or more rollers that you could double up, but, apparently, the design with no jumps was intentional.

      The trail is very accessible, so quicker riders should expect to catch up to slower traffic and some of the big, fast, descending berms seem to be catching out less experienced riders, so keep a lookout for riders down in those areas.
