Hi! Yes it is! Me and my partner go indoor climbing and it promotes teamwork, competitiveness and a really good workout! It is also alot about the trust especially when he is belaying me (holding on to the rope that you're harnessed to). We haven't done actual mountain climbing yet but that's on our bucket list for sure :)
It depends on whether both of you enjoy climbing? If yes then sure! If not then it’ll be really painful haha.
If your SO hates walking....... then gg lol
It depends.
