This guide introduces the climber to the bouldering, traditional climbing and sports routes at Dumbarton Rock. Known to locals as 'Dumby', this is lowland Scotland's premier rock-climbing venue, home to famous routes such as Chemin de Fer, Requiem and Rhapsody, and with a reputation for hard and technical climbing.

Dumby also cradles a collection of giant boulders, which host over 300 documented problems from easy to 8th grade level. Problems such as Pongo, Sabotage, Pressure, Sanction and Gutbuster are amongst Scotland's world-class bouldering test pieces. Photo-topos and textual descriptions bring clarity to complex routes (100+) and boulder problems (300+).

The guide features a contextual historical introduction by John Hutchinson, detailing the decades of climbing heritage for which Dumbarton Rock is internationally recognised.
