When one travels towards Ka'ena Point on Farrington Highway one will observe, just past Kaneana Cave, a finger of lava extending in the direction of the sea. This is a shore dive which has its entrance on the left side of the ridge. It is advisable to avoid the windward (right) side because the swell is extremely strong and can be dangerous, even in calm conditions. Snakehead cowries are the only real attractions along the ridge. Further away from the shoreline, however, the site becomes more visually appealing as the bottom topography slopes towards the main point of interest - a channel known as Makua Valley Ridge which stretches due west. A 250-foot swim leads to two small peaks that resemble a gateway to the channel. If one continues along the gutter one will come to a collapsed lava tube which resembles an amphitheatre. The top of the depression is at 33 feet and this drops to a bottom depth of 45 feet.
