At the entrance to the Crow's Nest field is a large depression which is the venue of one of the earliest Scout attempts to provide a swimming pool at Larch Hill. This area is known as "Matthews's Folly", after the then director of the campsite, Nicholas Matthews, who undertook the unsuccessful venture during the 1940s. Fauna Among the many inhabitants of the estate are badgers, squirrels and deer. The aforementioned bookmaker and former owner of the estate, John Coffey, kept racehorses on the site. One of these horses, named "Fast Pam", is reputed to be buried near the campfire circle. 21st century "The Hill", as it is known, has seen a number of changes in the 21st century. These include the construction of the pyramid building which houses those who work for Scouting Ireland on a permanent basis. The glass building also contains a function room named the Millennium Room which acts as a multipurpose meeting place for Scouts and Scouters. It also holds a bust of Fr. Tom Farrell, the founder of the Catholic Boy Scouts of Ireland (which came from the former national headquarters of Catholic Boy Scouts of Ireland at 71 St Stephen's Green and later at 19 Herbert Place) and a museum given over to national and international badges and mementoes from World Scout Jamborees. The campsite hosted one of the four national camps to celebrate the 75th year of Scouting Ireland (CSI) in 2002. It also plays host to the National Scout, Venture Scout and Rover Scout Fora each year. In Summer 2006, it hosted an international jamboree for Deaf Scouts hosted by the 191st Dublin Activities Activities onsite include orienteering, hiking, archery, high ropes course, and a zip line. The Tree Council of Ireland in conjunction with An Comhairle Oidhreachta, The Irish Heritage Council, has produced a booklet called the "Larch Hill Tree Trail" which details 25 of the tree species which are part of the campsite, including the main inhabitants, the Larch, Sequoia and the Sitka Spruce. Following the "Tree Trail" takes walkers to every corner of the site, taking in each camping field in turn. Larch Hill is near to the Dublin Mountains, and the broader Wicklow Mountains, and the Wicklow Way. Also nearby is the monastery of St. Kevin at Glendalough. The forest is used for bivouacking during the summer months. The forest in the North Eastern corner of the site
