Dived here on a calm day, entered and exited at the toilet bowl. No swell or waves. Parked my two wheel car just after the gate by the sign stating all of the warnings and restrictions. Similar to Honokahau harbor on the bottom. This site is called toilet bowl and at the far north end of the park is an actual ' blow hole' and excellent dive site! Just follow the road north and turn toward ocean at the end. Look for three or four twelve inch diameter white plastic pipes sticking out of the lava by the shore. Very slippery entry over LIMU seaweed growing on rocks. About thirty yards out it starts to drop to 200' plus. Strong currents and a very rough exit should be expected!
