The word “Lani Kai” literally translates to “Heavenly Ocean”.  It is not only described as "most beautiful" of all Oahu beaches, but Lanikai Beach has consistently ranked as one of the best beaches in the world. The sand is really nice and there seems to be plenty of room for everyone. Parking can be an issue here, as there is only street parking available..  As with any beaches here, plan on going early to get parking. You can see the famous Mokulua islands off-shore.  There is the Lanakai Pillbox Hike very close by, so you could make a nice day of it.
