Blue Mash Golf Course in Laytonsville MD is THE premier public golf course in the Rockville area. Designed by Arthur Hills and only 15 minutes from downtown Rockville, Blue Mash features a mix of links style, parkland, wooded, and water holes. There are no forced carries so it is manageable for beginners and high handicap golfers, and low handicap golfers will find its length from the back tees, strategic bunker placement, and devilish, well protected greens plenty of challenge.
