The only natural white marble arch in North America, spanning a 475-million-year-old water-cut gorge. The fully fenced paved walkway loops around the gorge and bridge — accessible with strollers. Interpretive signs explain the geology in kid-friendly language. Located 10 minutes from MASS MoCA — a perfect half-day combination.
