Lost Treasure Golf, also known as Professor Hacker’s Lost Treasure Golf, is a chain of adventure-themed miniature golf courses located across the eastern United States. Each course offers two 18-hole mini-golf adventures set amidst elaborate landscapes featuring caves, volcanoes, waterfalls, and cliffs, all designed to immerse players in the fictional expeditions of Professor Ephraim “Duffer” A. Hacker, a character inspired by early 20th-century explorers.
