Well, you seem to know more than your post indicated. Youdales is worth a look though, it’s a sort of hidden valley with some great views and excellent riding. Tracks are usually well maintained, but after all this rain might be a bit ordinary in places. There are other places to camp on the plateau, Kookaburra Hut being the best of them. You can hire the hut from my friend Eric Walsh if interested. (041869-1473) Have you ridden to Marys View or looked down the valley from McMillans Hut? Carrai Ride Report
Also the old traction engine and Felters Creek Falls.

I have 100 acres with a shack at the bottom of the range. Its a good kickoff or rest point for these adventures.
