Day 11: Kohanaiki Camping
The south-west part of the island offers the best whale watching possibilities. You can even see those giants from the shore. But make sure to bring your zoom lens as they can be quite far away.
Petroglyphs are stone carvings created by the ancient Hawaiians. Their exact meaning is not known but they show events like birth, hunt and other major events. Close to the petroglyphs is a beach with black volcano stones mixed with white remains of the corals.
At Kealakekua Bay you can rent a kayak and look for resting dolphins as well as snorkel at the Captain Cook memorial. It is probably the best snorkeling spot on the island as the corals look super healthy and there are many colorful fishes. Only a short drive further is another snorkling spot called 2-step. And there you have the chance to see Spinner Dolphins.
