The Climbing Wall is a giant wall which Greek campers climb at Camp Half-Blood. They must climb quickly or it will clash with the other wall, causing lava to pour from the top, and boulders to fall on whoever is climbing at the time.
The climbing wall is mentioned when Percy Jackson talks about his days after having found out he is a child of Poseidon. He says that Grover Underwood could quickly climb up to the top and that Percy barely made it up. His Camp Half-Blood t-shirt had smoking holes in it and the hairs on his forearms were singed off. He later says that he could climb to the top on the best level without getting burned.
