Mile Marker 4 is small beach with easy entry that offers great snorkling and shore diving in Kailua–Kona, Kona Coast, Big Island, Hawaii. Several lava tubes may be found a short swim to the left.
The first part features snorkling through different varieties of coral and then switches to scuba gear in a shallow dive.
The video quality is good but the coral is almost lifeless compared to some video here. It is a shore dive and easily found by rental car if you plan on snorkling or diving in the Kailua-Kona, Hawaii area.
