Mt. Washington is in northern New Hampshire, and is a classic old hotel and four season resort. You don't have to be a guest at the hotel to play the courses here, but there's a slight discount if you do. They have an older 9 holer, built in 1891, which has been touched along the way by a variety of designers including Gene Sarazen, Ken Venturi, and more recently Brian Silva to finally restore the course.
It's set along the Ammonoosuc River, and is a traditional course of 3,500 yards, par 35. The 18 hole championship course was designed by Donald Ross in 1915, and is a par 71, 6,638 yards, 118 slope from the back tees, and was restored by Brian Silva to its original design in 2008. The result was restoration of Ross's original plans, trees removed, bunkers returned to the Ross design, and reconditioning of the small to mid-sized greens. Fantastic setting with Mt Washington in the background.
