Green Wave is a short, easy mountain biking loop in western Massachusetts, about 0.6 miles long and roughly 3.6 miles from South Williamstown. The route is a loop that starts and ends at nearly the same point, with a low point of about 1,550 feet and a high of about 1,619 feet. The climb is back-loaded, with the steepest stretch at about 0.5 miles in, where the grade reaches 10 percent. The total gain is about 260 feet, and the total loss is about 300 feet, so the route is a low-commitment ride that works well as a warm-up or a quick lap. Summer is the most comfortable time to ride. Typical averages from a nearby weather station in Grafton, New York, show July highs around 78°F with lows near 59°F, while September cools to highs around 69°F. Several other mountain biking routes sit right next door. POC Trail and Learning Curves are each about 0.1 mile away, and The Cirque is about 0.2 mile away. For a change of pace, Shepherds Well Trail is about 1.4 miles away.
