This hike starts out boring and continues to be not very interesting until near the end them WOW WOW WOW.  The last half mile makes it worth while.  When you get to the handrailings, go around to the right and down a ledge or two and see the lake and Mexico in all its splender.  On the return take all the little side trails to break up the monotonous trip back.  Extremely easy walking, but miserably hot in summer. Very good for biking to cover the flat desert faster.
