Climb Newcastle Grade Systems

At Climb Newcastle we use the Fontainebleau grading system. Fontainebleau in France is the most extensive bouldering area in the world and its use as the primary grading system has now been established in the UK.

Our problems range from Fb 3 (very easy) to around Fb 8a (very very hard) or even harder. Each circuit is in a band of difficulty and overlaps with others. This helps progression between the colours. We also mark on our circuit charts the easiest and hardest of each circuit to assist you.
