The Blow Hole

The floor gradually drops off to 100 feet, lots of corals, fish, etc. Navigate carefully because immediately north of the blow hole is an another cove and it is easy to mistake this cove for the one you went into. It isn't a big deal to go back out of the old cove and enter the right one, but you can't always see the arch until you get all the way into the cove. WATCH YOUR AIR. As always the case when diving Hawaii watch the waves and wind. The visual effect of the arch, both in and out, is quite stunning. There are some little caves in and around the cove that are very interesting; a flashlight is good. On the Big Island, go North on Highway 19 from Kailua Kona about 7 miles to Natural Energy Road (Last road West before the Airport). Drive about 1 mile West to the point where the paved road turns north. Turn South on the Dirt road. Drive (VERY CAREFULLY) about 500 yards to a gate which should be open during the day. Go about 100 yards past the gate and look to the ocean. You will see 3 large lava heads along the ocean. Within the lava heads is a cove with an arch on the ocean side which is partially submerged. There is a nice exit on the South side of the hole right by a rusted piton which is there. Gear up and jump in to the cove. Drop down to the bottom, about 15 feet, and swim out under the arch.
