Hawaii Magazine Sling Iron at a Hilo Beach Park and Horseshoe Court Where else in Hawaii can you find family friendly tidepools, comfortable pavilions as well as an official horseshoe court? Jan 26, 2021 There are numerous reasons why visitors and locals love Onekahakaha Beach Park. Just south of downtown Hilo on Hawai‘i Island’s eastern shoreline, this family-friendly beach park is well-suited for those traveling with keiki (children). Lifeguards are on duty year-round. The beach’s expansive sand-bottom cove is protected from the ocean’s turbulent swells by a wall of lava rock and boulders. Sea cucumbers, anemone and wana (sea urchin) gather in the tide pools surrounding the main bay. And numerous pavilions and grassy, tree-covered sections of the park provide ample room for a picnic. However, what really makes this beach park unique is that it is home to one of the only legitimate horseshoe courts in the state.
