Isla Taborcillo, also known as John Wayne Island in the media, is a tiny private island located twenty-five miles off the coast of Panama. Taborcillo was once owned by Western actor John Wayne, though it is currently owned by Ralph Hubner, an Austrian businessman and the founder of Who is Who, a publishing company.

Taborcillo is lovely, and it’s not all island. It has been transformed into a resort-like paradise. It has a theme park, resort hotel, and is a tourist hotspot near Panama. A part of the island is a wildlife sanctuary, where birds like egrets, hummingbirds, and brown pelicans nest.
