There is no adventure sport more secretive and alluring than caving. Hidden deep in the Berkshire Hills are miles of underground passages with hidden entrances off the beaten track. Many of these caves were just discovered within the past 10 years! We begin the week at Kroka Village exploring abandoned mines in the area and practicing vertical rope skills. From here we head west and establish a wilderness camp at the base of Mount Greylock. With map and compass and our traveling gear, we will set out each day to explore the region's known caves and search for those that have not yet been found. We will swim in pristine waterfalls, descend into abandoned quarries, and visit natural marble bridges. We will cook delicious meals over the fire, share stories, and learn a wilderness craft. The journey ends with a 3-day expedition to a mountain peak and a day-trip through one of the longest and most notorious caves in the Northeast.
