Peak climbing involves ascending smaller mountains that require basic mountaineering skills, such as using ropes, crampons, and ice axes. It is more challenging than trekking but less difficult than major summits like Everest. Popular peaks for climbing, especially in Nepal, include Island Peak, Mera Peak, and Lobuche East. Climbers need physical fitness and some technical training to handle higher altitudes and rugged terrain. It offers an exciting adventure for those seeking a higher level of challenge in the mountains.
