[Grammar] None of us had ever been caving before

[yi-ing]

In terms of collocation, what is the correct verb for the noun "caving"?
Can we say "I do caving or I am caving"? are the bold sentences OK?

I had the most amazing adventure last year. I spent an afternoon exploring the caves near my village with a group of friends. None of us had ever been caving before, so we went with my friend’s brother, who’s been doing it for ages. He supplied all the equipment and showed us what to do and how to stay safe.

Your sentences seem OK. I think either "been caving" or "gone caving" would work.

The term "spelunking" is used here. As unusual as the word sounds, it is more familiar to me.

You meant I could say "I am caving". Right?
How about "I do caving once a month" ?
