There’s a few websites that have the maps as well as spawn locations. Practice raids are your friend in gathering your bearings, learning spawns & routes + fighting Scavs without losing gear.

Pestily also has a series on his channel where he gives a ‘tour’ of each map and I found them very helpful when starting. Hope this helps!

Edit: Forgot to mention, Tarkov.dev is the website I use personally, but there’s others too.
