Blue Mash Golf Course in Gaithersburg is a public course designed by architect Arthur Hills. Its routing moves through a variety of settings, combining links-style ground with parkland stretches, wooded corridors and holes shaped by water.
There are no forced carries, which keeps the layout playable for beginners and higher-handicap golfers, while the overall length, strategic bunkering and well-defended greens give stronger players plenty to think about.
Practice facilities include a 9,000-square-foot putting green, a grass-tee driving range and a short-game practice area, with instruction available on site.
