In total there are currently 65 golf courses in Iceland. One of them has 27 holes, fifteen are full 18-hole courses and the rest are 9-hole courses. In relation to the number of inhabitants (320,000), there are more golf courses in Iceland than anywhere else in the world; one for every 5,000 Icelanders.
Around 2007, however, disc golfâs popularity exploded unlike it ever had before. While it had taken 30 years to establish 1,861 courses in the U.S., the country saw 1,319 added in just the next six years. PDGA membership nearly doubled during that span.
