Ala Moana Bowls

South Shore, Oahu, USA (HI)
🪸Sharp reef⚠️Shallow😮‍💨Hold-downs👥Crowded

Ala Moana Bowls is the Pipeline of Town—long, hollow, fast lefts over a shallow man-made reef created during 1950s harbor construction. When solid south swells arrive, it produces draining barrels that rival anything on the North Shore for intensity.
