One that immediately comes to mind is Royal Hawaiian Golf Course on Oahu. The course is routed mostly through a dense jungle situated between mountain ranges.
The course was built during the early 90’s golf boom on the island by a Japanese developer who had grand plans for 36 holes and a residential development. Like several other courses, including Ko’olau, the full plan was never realized due to the economic downtown. The Dye family was involved although it’s unclear exactly who spent time here.
Royal Hawaiian is plagued by its location that receives over 120” of rainfall annually. Poor soil conditions exacerbate the rainfall and the jungle setting means the the course is continually battling the encroachment of the jungle itself. Fairways typically end abruptly with severe fall off into the surrounding jungle habitat.
While other courses mentioned on this thread are built in locations where golf courses are typically not found or routed in a manner that requires a golf cart, modern technology has enabled us to overcome most unnatural environments. Royal Hawaiian, however, is actually up against nature and the massive amount of rainfall that contribute to generally unplayable conditions most days. In the words of their superintendent, it’s a “maintenance workers nightmare” where they are unable to use mowers in many areas of the course, have to spray fungicides weekly on the greens, and aggressively keep the jungle from consuming the course.
While I’m sure there are ways to throw money at some of their problems, Royal Hawaiian is simply a course should not have been built in this environment.
