LANIKAI PILLBOX TRAIL

in Kailua is an absolute must-do if you are heading to Oahu.  It is a short, but steep, hike to two World War II bunkers.  The hike is about a mile up and the view is unbelievably amazing.

Most of the hike you have the ocean breeze to cool you off but don't let that fool you - make sure take sunscreen and water.  And, I would recommend wearing shoes, not sandals.

I give an enthusiastic two thumbs up for this hike.
