Ala Moana Bowls is the perfect little left bowl set up with great rights and lefts. Remember to always be aware of and respect the locals.
To get there, go to Ala Moana Harbor/Boat parking lot near Hilton Hawaiian Village. Walk along the rock jetty that parallels the boat harbor on the right. Jump off rocks and paddle right towards the deep water boat channel, there's a huge buoy out there. If it is on, you will see a thick sucky left barrel coming through. Have fun, get barreled and be safe.
