Start in the grey square that resembles a window. Try to do a four-point start with your body perfectly framed inside the window, but don't worry if you can't. Reach up to some slopey underpinches and edges, then top out above. A classic climb. Make sure to pad the ivy so you don't get itchy.

From the North entrance of Olin, walk east along the path with the buildings to your left until you reach the arch under which is the entrance to Lopata. Go through this arch to immediately reach the stairs. To the left of the stairs is where the Window is.
