Wrigley Memorial and Botanic Garden

Named after William Wrigley of the chewing gum empire, this island oasis focuses on plants that grow only on the Channel Islands. The structures, influenced by Mission and Art Deco architecture, are adorned with tiles that were handmade at the now-defunct Catalina Pottery. Even though it's a small garden on a small island, it attracts about 70,000 visitors every year.
