First time visiting these trails but I hope to return soon. Trails are quite smooth and fast. Rode a ten mile loop from upper trailhead. Made it most of the way up the summit spur off the Outback trail but it was very rough, loose, steep and nasty. Since I was by myself I decided to head back down and take it easy. Fast, fun, flowing trails. Lots of fun. Great place to take the family for a ride. Trail surface is like riding on crushed, packed pumice. Very nice. Relatively gentle grades on the ride up and huge smiles on the way back down.
