The easiest and initial approach to constructing a refuge is to use what's already provided in nature, such as a cave or rock overhang. Once you've scouted out some existing features, all you need do is scavenge some materials to enhance it. These include logs, branches, palm fronds, vines etc. You can build walls, a roof or ground cover for insulation and comfort. Be sure to investigate for insect and animal activity before finalizing your decision to stay.
