Clear to ride but small branches and leaves all over. A few trees down after the wind but they have been shifted out of the way.

Track is in good condition throughout but access via Widdershins and Barnicoat Ridge still a major issue.

      I presume nothing has changed on Glider Road? Not willing to hike the fire break!

      Getting to this trail is pretty tough going up the glider Rd, which is impassable towards the end as there are multiple trees down so you have to backtrack and then hike-a-bike up the firebreak track.
      It definitely is a fun ride down and the native forest is really beautiful.

      Involution is all clear after the weather bomb we have had. There was a tree down up the top which was partially on the trail - now completely cleared away. Large rocks before the first creek crossing are sorted too.

      We hope you've been enjoying Trailforks!
