Climbing the Via The Brothers
From The Garden in Keene Valley, New York (reservation and fee), Big Slide is popular via the Brothers ridge, with open ledges and excellent Great Range views along the way, or via Slide Brook. The rock steps are steep with a short scramble near the summit. Ledges are slick when wet and exposed to wind. A relatively accessible High Peak often done as a loop, it draws crowds on nice weekends. Start early, carry water, and enjoy the views from the Brothers.
