Each year from November through February, thousands, if not millions, of Ladybugs red bugs converge to Reinhardt Redwood Regional Park in Oakland, CA. It's a spectacle to be seen!
We go on a Ladybug hike each year (they migrate here for the winter) in Reinhardt Redwood Regional Park in Oakland, CA. Scouts bring a small backpack with the 6 essentials, and layers layers - it can get cool in the shade of the redwood trees.
