How to Track Down All Six Portal Variants by Biome
If you want to find every themed gateway structure in a single world, random wandering will leave gaps because the six portals are split strictly between open landscapes and wooded biomes.
Using Pale Gardens as a Hub
If you locate a Pale Garden, search it thoroughly. It is the most versatile biome for portal hunting, capable of spawning five of the six variants: Soul Sand Valley, Basalt Deltas, Bastion, Crimson Forest, and Warped Forest. Only the Seeping Portal (Nether Wastes) skips it.
Running a Complete Two-Part Route
To see all six structures without relying on rare biomes, split your expedition into two legs:
1. Open-Biome Leg: Travel through Badlands, Deserts, Savannas, Savanna Plateaus, Windswept Gravelly Hills, or Snowy Plains. Every one of these six biomes can generate all four non-forest gateways (Soul Sand Valley, Basalt Deltas, Bastion, and Seeping). You can also check Swamps or Mangrove Swamps specifically to isolate the Soul Sand Valley ribcage and portal.
2. Forest-Biome Leg: Head into any standard Forest, Taiga, Jungle, Birch Forest, Dark Forest, Cherry Grove, or Wooded Badlands. Only the Crimson Forest and Warped Forest portals spawn here, making every breach you spot guaranteed to be one of the two forest variants.
