Long park behind the campground and the coastal dunes, with pleasant trails under tall eucalyptus trees. The amazing Monarch butterflies migrate here over several hundred miles from the Sierra Nevada, Oregon and Washington State, to overwinter in the mild climate, hibernating several months high up in the eucalyptus trees. Volunteers with telescopes make it possible to find and see them, and provide information. The monarch habitat destruction by agriculture, pesticides, and climate change has caused the famous migrating population to colapse. From previously hundreds of millions to just a few thousand. Extinction is a real risk in the near future.
