Diamond Head

   This is a touristy place that is fun to go to, and only takes a couple hours.  Volcanic activity created 761-foot-tall Diamond Head, located on Waikiki's eastern border.  It is a "tuff cone," formed some 100,000 years ago when an eruption of volcanic ash eventually hardened into solid rock.  It is worth the 25 minute hike to the top of the crater, to get a full view of Honolulu, and all of it's glory.  The hike is fun, and is not to hard.  

   There are rails to hold on to where it gets rough.  There a few tunnels that you have to walk through, and for some reason, there are no lights in these tunnels.  The tunnels are long, and in some areas in the tunnel, it can be completely pitch dark.  For this reason, you will want to bring a good flashlight with you for this hike.
