One of the largest and deepest sea caves in the world. Santa Cruz Island is part of the Channel Island National Park chain. The quarter mile deep, 100' deep Painted Cave features an entrance ceiling of 160 ft tall and is named for the colorful lichens, algae and mineral deposits that adorn the cave. If you show up in spring, you'll likely spot a waterfall spilling over the cave entrance.

Though difficult to access, the only way to reach the cave is charter a boat and paddle some kayaks into the cave. If you're planning on visiting the Painted Cave, I highly recommend camping in the National Park at the Scorpion Bay anchorage; bring some snorkeling gear and enjoy the clear visibility and copious ocean wildlife. At night during the summer, one can see blue bioluminescent algae on the ocean surface offering a transcendental experience for first time witnesses.
