Suggestions for new lens

So I own a D3400 that I bought 8 years ago and I only used it with the standard lens it came with. I’m looking to get a new lens and revive my photography hobby but I’m not sure where to start. Since I don’t have money to buy multiple right now, I’m looking for something I can use to take outdoor photos (I like going hiking, going on safaris and such) but also my graduation is nearing so I might use it for that as well. But mostly travel stuff.
