The US Open took place on the Erin Hills Golf Course in 2017. Need we say more? The US Open is only held on the absolute top courses in the States and the Erin Hills Course was designed especially for this mega-tournament. The course combines modern elements of golf course design with traditional ones in a dream landscape once formed by glaciers. One hole is more beautiful than the next - the fourth is perhaps the most challenging: The fairway is flanked by rough on the left and dangerous bunkers on the right. The green with bunkers at the front and marshland at the back requires the utmost precision, otherwise you will be playing in water or sand, which will cost you points.
