I'm taking a non climbing colleague climbing and she was worried that people are going roll their eyes at climbing next to a beginner.
I explained that a) climbers are nice people and b) a sunday league footballer is never going to share a pitch with Ronaldo but you can have a beginner route in the same piece of rock as something that is elite/if not world class.
So I was wondering where you have the biggest grade difference in routes next to (or all most next to) each other. For example a crag picked at random; Black Rocks has Moonchild (E7 6c) right next to Pine Tree Gully (D). Extra marks given if BOTH the routes get stars
