A drift-dive wall on the east coast of Isabela, dive-only, formed where a lava flow from Wolf Volcano drops off underwater. It is known for manta, mobula, and eagle rays — schools of up to 50 mobula are reported — plus hammerhead and whitetip reef sharks, tuna, and large schools of fish. Currents are moderate to strong.
