Old Marsh is near Kennebunkport off I-95 to the west at exit 19.

The course lumbers through the thick forest over rolling terrain with the Webhannet River slicing through the lower half of the layout. There's generally ample room off the tee as the course winds through numerous slight doglegs along multiple ponds and the River with an abundance and variety of sand bunkers in the fairways and greenside. It was designed by Brian Silva and off the tips plays to 6,523 yards, 71.7/135, course/slope with three shorter tees.
