I kinda like to imagine a monk that lives in the wild. Kinda like a druid, but I don't really care for shapeshifting so I'm not entirely sure how useful that would be. Rangers also live in the wild, maybe? I'm not sure if either of these classes blend with monk well. 

Any idea on how I can make a monk in turned with nature? I like the idea of a monk that's kind of a hermit living in the forest. Maybe a little house in a tree or a hut or something. 

Thoughts?

For flavor, just taking the Hermit background would suffice.

For mechanical blending with nature, multiclassing with Druid, Ranger, or Nature Domain Cleric work fairly well because they are Wisdom casters, which is a primary stat for monks.

If you wanna go full monk, the most nature-esque subclass is probably Way of the Four Elements. I could also see Sun Soul if you wanted to focus on the idea of sunlight

Unless you have a specific concept in mind that involves mechanics outside of monk features you can pretty much do everything you want via background as Kaboom979 suggested or just RP flavor.

Yes, Four Elements monk has the nature feel, but really any monk subclass could work. Open hand, or any subclass, can be flavored as fighting mimicking animal fighting (Tiger, Mantis, etc). Kensei could be a protector of the forest. Drunken Master would fit with the hermit idea of the lone master in the woods who just happens to drink too much (or at least act like it). 

pretty much there is no limit on flavoring the class to fit what you need. But as has been mentioned Druid, Ranger, Cleric can all work well being Wisdom based. Just realize if you are focusing on monk you will lose out on Ki points the more you multiclass 

Cool thanks! Thanks for the advice. 

Another option you might consider is picking up Magic Initiate (Druid) or maybe Fey Touched (Wisdom), this won't slow down your Monk progress like multiclassing does, and you should be able to squeeze a feat onto a Monk build.

Magic Initiate has the advantage of cantrips you can use all the time and the best selection of nature spells, but if you build for a 17 in Wisdom then Fey Touched gives you access to some decent options while still allowing you to advance your Monk's ability scores. Plus it still has some good spell options such as Animal Friendship, Beast Bond, and Speak With Animals, as well as the excellent Hunter's Mark which can boost the damage on all of your attacks by d6 for up to an hour, though it does require concentration and your bonus action to cast/transfer it, but it has a definite tracker vibe built in.

I'm playing a multiclassed Monk into Cleric, and while I've been enjoying it immensely, doing it early means you delay Extra Attack and Evasion which isn't ideal, and you'll lose even more progress if you want to go Ranger (as you really need at least three levels to make the most of it, whereas you can get by with just one or two in Cleric or Druid). You do however get a lot of extra options. For me I found my damage was really lagging behind for a while until I finally got my Monk level up to 5th, so if you don't have a very clear idea of what you want from multiclassing I wouldn't do it until level 6 at the earliest (or maybe 7, as Monks get a sub-class ability and Stunning Strike at 6th).

I might also consider Tabaxi or Shifter race to get a nature flavor....but I do like monk / druid multiclass as a solid mix.
