What is the name of the activity involving staying in tents?

The question was what is the activity involving staying in tents. The answer should be tenting .you don,t need a tent to go camping. You can do that underneath the stars. Or a camper van. You need to rephrase your question.

Tenting is a valid answer.

In Hawaii, we could camp on the beach without a tent, just straight up under the blanket of stars and the relaxing sounds of the ocean calmly sweeping along the shoreline! 👍😎

I love to camp an be fishing for supper 😋.

OK, so what is tenting?

It ain't for rookie members of the US Marine Corps. It's more of a family affair.
