This document discusses peak bagging, which involves hiking to the top of mountains. It describes several lists of peaks that can be bagged, such as the Hundred Peaks in Southern California and the Seven Summits, which are the highest points on each continent. The level of effort required ranges from simply getting out of your car at the top to multi-day backpacking trips. An example peak mentioned is Mount Gould in the Sierra Nevada, which the author has bagged as a 2-3 day backpack and has also day hiked to Kearsarge Pass near Mount Gould.
