While any map in Escape From Tarkov is going to take Escape from tarkov Money a while to learn, some are better than others from a beginner's perspective. Customs is the most commonly suggested map for beginners, as it houses a fair amount of early-game tasks and is not too hard to learn. However, it is a PvP hotspot for the entirety of the wipe, so you could get yourself in a bit of trouble against players who have far better gear than you.
Woods is alternatively a really good choice for beginners wanting to ease themselves in. Not only is it harder to run into other players - so you can ease yourself into the game a bit better - but it also has a lot of great loot that is left relatively untouched. It is a harder map to learn for beginners though, as its sheer size combined with the fact it is - as the name suggests - mostly just trees can make navigation quite tricky.
The main thing you'll want to be confident with when you're trying out a new map though is that you know where the extracts are. Since there are no real-time maps in Escape From Tarkov for you to use, knowing how to navigate yourself through distinct landmarks is a must as otherwise you can get lost very quickly.
Using websites like MapGenie can go a really long way in helping you figure out where everything is, and until you properly learn each map it is very much recommended that you keep one up on a second screen if possible when playing.
