For lunch on the boat, we had shrimp with rice, very very tasty.
After a siesta until 2:30 PM we left the boat for the Sullivan Bay lava flow, a fresh and huge lava flow. The lava flow was created only 100 years ago and it created 10 square kilometers of new land. It is so new that it wasn't there when Charles Darwin visited the islands in the first half of the 19th century. The lave is pure black, and you can see where the it flowed and rippled.
After the lava flow, we went snorkeling from a nearby beach. We saw some fish but not too much. Others saw a small shark and a ray. We also saw some sally lightfoot crabs eating on the tidal rocks:
