CLIMB covers all means of physically going up or reaching the top of something using one's hands or feet or both - climbing a rope, a mountain, or the stairs. CLAMBER suggests a difficult or awkward climb that requires the use of both hands and feet; clambered up the rockface, the ladder, or aboard the ship. In actual usage, clamber is sometimes used for a more crawl-like action: clambered along a 40-foot log: clambering among the ruins
