This is a DIFFICULT hike and is NOT for beginners. Please note that the elevation is steady with very few breaks. However, the views are awesome and the terrain is scenic and varied. Shade is somewhat minimal, so bring lots of water and electrolytes (i.e. Gatorade). Wear sunscreen and a hat.

Civil twilight is at 8:52 pm. I don’t anticipate being out after dark, but it’s good to be prepared. I always bring a headlamp or flashlight. Don’t rely on your phone.
