Stand up paddle boarding is a must do when you visit the North Shore of Oahu.  A 45 minute paddle  up the Anahulu River will thrill young and old as you paddle past green sea turtles on smooth water.  If you go in the later afternoon you will see the sun setting on the horizon and fall in love with colors too orange to tell.  Stand up paddle boarding is easy but if your a bit unsure get a lesson.
