What Are Some Crazy Adventures My Bffs And I Can Go On In The Future?

There’s 4 in our group, an Indian girl who’s been my BFF since forever, a nice petite farm girl, and the geek of the group who is a chatterbox. The Indian one can be a ‘me me me’ person sometimes, and she might be picky about where we go. The farm girl seems o be always up for an adventure. The geek likes to take risks I think.
We can’t go now or anytime soon, but in like 10 or 5 years at like maybe 25. So, any ideas for a fun adventure with my BFFs? And by fun, I mean crazy. Like to the Amazon rainforest or something lol. Thanks!!
