The main change to Twrch is the lack of trees since the deforesting started a couple of years ago. The long zig zag climb from Bishop’s Finger up to Airstream is now totally devoid of trees, as is Castle Valley and Dragon’s Tongue.
The black option at Airstream has been rebuilt as well and now has more table tops.
Cafall is great with some good downs on it, but as mentioned above about 3km of the top is closed because of the forestry work going on.
As of this morning the initial climb shared by both trails from the car park up to the Scenic Drive ticket office is closed for 2 – 3 weeks so you’ll have to use the road to ride up.
