The crimson forest is a forested biome in the Nether, home to hoglins and piglins. It is one of two Nether biomes where players are able to acquire wood without returning to the Overworld. This forest is the only place where huge crimson fungus trees grow naturally.

Description

The crimson forest is the second most common Nether biome, making up 22% of the Nether by volume, and can generate next to any other Nether biome except for the basalt deltas.

Crimson forests are dense and have a crimson color scheme. The forest's fog is dark red and blazing particles are seen floating. Piglins are often seen in this biome in groups of 3-4. Zombified piglins also spawn, but in fewer numbers, and striders appear in lava lakes that generated within the biome. This is the only biome where hoglins naturally spawn outside of bastion remnants.

The forest floor is mostly covered with crimson nylium, with some netherrack and Nether wart blocks generating on the surface as well. The most frequent vegetation of the biome includes crimson fungi, crimson roots and huge crimson fungi, along with weeping vines that hang from the large fungi and Nether wart blocks from the ceiling, and lone shroomlights that provide light within the huge fungi. Warped fungi, though less common, also occasionally generate, naturally keeping hoglins away from affected areas. Just like in the rest of the Nether biomes, fire and lava are very common, with the latter appearing as lava springs or whole lava lakes. Glowstone blobs also spawn on the ceiling like normal.

Nether fortresses can generate in this biome, along with bastion remnants and ruined portals.

Mobs

The following mobs naturally spawn here:

In **Java Edition**
Mob	Spawn weight	Group size
Monster category
Zombified Piglin	¹⁄₁₅	2–4
Hoglin	⁹⁄₁₅	3–4
Piglin	⁵⁄₁₅	3–4
Creature category
Strider^{[note 1]}	1	2–4

↑ Adult striders have a 3.3% chance to spawn being ridden by a zombified piglin holding a warped fungus on a stick.

In **Bedrock Edition**
Mob	Spawn weight	Group size
Monster category
Zombified Piglin	1	2–4
Piglin	5	3–4
Creature category
Strider^{[note 1]}	20	2–4
Hoglin^{[note 2]}	20	3–4

↑ Adult striders have a 3.3% chance to spawn with a saddle. They are supposed to spawn with a zombified piglin with a warped fungus on a stick but they don’t due to MCPE-236161.
↑ In Bedrock Edition, hoglins count toward the animal cap instead of the monster cap.

Trivia

When the crimson forest was announced at MINECON Live 2019, which happened before the first Nether Update snapshot was released, it was known as "Nether wart forest". In the announcement, however, it was called "Nether wart forest red".
Most of the ambience in the crimson forest was made with balloons, which Samuel Åberg says creates a disturbing feeling of something stretching and forcing itself to bend.^[1]
The crimson forest's music track, Chrysopoeia, is named after a term in alchemy that refers to the transmutation of base metals into gold.
