       Perfection, traction is all time right now. Gritty dirt doesn’t get too slippery on the rocks

       Definitely only a trail for advanced riders. There are some huge slabby rock obstacle course drop offs that are not for everyone.

       Agree with below comment, this trail is a step above the adjacent black diamonds. scout the blind rollers first if you’re not a high confidence rider

       Why are E bikes Discriminated against using the trails? There are plenty of people like myself with injuries or disabilities that can only access the trails with the help of an E bike.

       Are you asking about Rocky Peak specific trails or E-Bikes in general? Personally, I think Rocky Peak is the most acceptable for E-Bikes because most of the trails are downhill only and no one is biking up Santa Susana for fun (unless you're on a road bike)...

       This trail is no joke. Steep rock slabs drops everything. Don’t recommend riding alone for the first time.

       This is the definition of GNAR. AM and Trail bike maybe inadequate depending on skill level. Recommend FR or DH bike. Ungroomed trail with not much flow or jumps. A lot of drops into technical rocks where you can't build much speed without the travel. Technical with up and down transitions into steep descent at the end. This is borderline double black diamond.

       Should remove or cover all the stupid hiker arrows/rabbits that lead to the dumb swing. Redo them so they lead all the hikers off the mtb routes or maybe off a cliff.
