I love the west side Oahu so much because going to the west end point you will pass about 20 miles or more of coastline with sandy beaches ans also rocky spot for shoreline fishing. It's the dry and hot side of the island but here you can see the highest mountain of the island of Oahu which is the Waianae range where the air force place their radar dome.
This picture above is still part of the Waianae range and this plains and mountains here are military zone, here the military trains, I think they are playing the war game here and practice firing and bombing.
