Although somewhat randomised, many of the zone layouts throughout the Path of Exile 2 campaign are fairly readable which can help making get through them more quickly.
This guide covers layouts in Act 1.

The images in this guide were created by looking for consistent patterns in each area to create a generalised method for running each zone. The images you see won't perfectly match what you have in game, and your zone orientation and locations of points of interest may be different, but these images do serve as a good guideline. Try to understand the pattern they demonstrate rather than blindly following them and expecting your in-game maps to look identical.
Big thank you to the Campaign Codex team, especially Haddoq for his analysis of zone layouts as well as the early layout images that you can see in this guide, and also to Guitaraholic for his huge amount of data collection, collation as well as the Campaign Codex Discord server which players can join to share their layouts and insights.
