The grade ranges from 15% to 25%.  Some parts of the trail have hand rails you have to use to get up.  The heat, constant sun, and the stair step climb to the top proved to be pretty tough.  For another shot of the steepness of the trail click here.

With all our stuff packed we tried to carry as little as possible.  This included water.  Bad move.  We needed a little bit more than we had which was 40oz.  We also thought we could take it in our tennis shoes.  Another bad move.  Boots would have worked better.  You can see how rocky the terrain was.
