just wondering what the differences are:
Peak bagging (also hill bagging, mountain bagging, Munro bagging, or just bagging) is an activity in which hillwalkers and mountaineers attempt to reach the summit of some collection of peaks, usually those above some height in a particular region, or having a particular feature.
Peak bagging can be distinguished from highpointing. In peak bagging, the targets are the peaks of mountains or hills, and the popular lists usually require that the target pass some threshold of prominence. In highpointing, the goal is only to reach the highest point in some geographic area (e.g., county, state, or country), whether or not it is a peak.
