This is a great site that's less than 5 minutes from Kona town. The park's just off the Old Airport runway, so there's always ample parking unless the fair is in town (they cover the runway with the rides, etc.). One of my first introductions to the site was two local divers exiting amidst high surf, one with a bloodied hand that he shredded on the rocks. They told me to go elsewhere, and I took their advice. If it's calm, the rocky entry is a bit slippery, but only moderately difficult. Great drop-off, and interesting reef and marine life.
