Backpacking can be a noun or a verb (gerund).

Verb: They went backpacking this weekend.

Gerund/Noun: Backpacking is a fun activity to do as a family.

I'm not sure if it is used as a participle or not. (Because ending in -ing and everything.)

Backcountry com have the highest quality gear for backpacking, and camping.
