The difference between survival camping and tent camping…
…is the need to keep oneself alive vs living outdoors for the enjoyment of nature.
Survival camping is when you have only a few basic items and you need to find food for yourself (fishing, hunting) in order to stay alive.
Tent camping is a form of outdoor recreation camping where you bring with you everything you need for an enjoyable stay with nature. You bring food, sleeping bag, tent, etc.
