Laniakea is known by tourists as “Turtle Beach” because there are often turtles found resting on the beach. There is usually a volunteer there to protect the turtles and answer questions you may have.
The best part is being able to swim with turtles in the small bay. You can usually find 3-4 turtles and they are very used to humans. Just don’t get too close and don’t touch the turtles–it’s illegal in Hawaii.
