About Quincy Quarries

Quincy Quarries Reservation is greater Boston's urban climbing venue — a set of about 21 disused Quincy Granite quarry walls arranged in a near-circular pattern around Little Railroad Quarry, ten miles south of downtown Boston in the Blue Hills. The pink-to-grey Quincy Granite is the historic building stone used for the Bunker Hill Monument. Because the walls face every cardinal direction, the crag's aspect is genuinely various — chase sun or shade any time of day. Mountain Project's top-ranked routes span the friendly grade range: White Knight (5.5, S Wall), Black Knight (5.6, S Wall), Layback (5.7, J Wall), Outside Corner (5.8, K Wall), and Pins (5.9+, K Wall). Walls are lettered A–S rather than named. MassDCR-managed, free public access. Bolting is prohibited; chalk is allowed. Historic bans were lifted in 2003 and climbing has been open since. Car break-ins are the main concern — do not leave valuables in the lot.
