Easy access and good parking at Waiolena Beach Park. Like another reviewer wrote, look for the 3 pavilions along the ocean...the dive site is right out from the steps that go up over the lava rock wall, just west (towards Hilo) of the pavilions. We got up to about 60'. Nice coral. Easy dive when the surf is down & it hasn't rained in a few days. Definitely worth your time. You can get equip down the road at Hilo Ocean Adventures. Nice outdoor showers to rinse off yourself and your gear after your dive.
