Simple Biomes Expansion 1.21.120+

Have you ever felt that the world of Minecraft could use more variety, or that exploring new terrain no longer feels as surprising as it once did? If so, this add-on is made especially for you.

This add-on introduces up to 95 brand-new biomes, all seamlessly integrated into the game without adding any custom blocks, items, or entities. Every biome is carefully crafted using only existing vanilla blocks, ensuring that the world generation feels natural, coherent, and fully compatible with the base game. Among these 95 biomes, 6 are entirely new cave biomes, designed to expand and enrich underground exploration.

The added cave biomes bring more diversity to the depths of the world, featuring unique underground atmospheres, varied terrain formations, and distinctive block combinations, all while remaining faithful to the vanilla aesthetic. Together with the surface biomes, they create a much more complete and immersive world, both above and below ground.

You will encounter a wide range of environments, from biomes that feel like they should have always existed in Vanilla Minecraft, to more imaginative and fantasy-inspired biomes that still remain visually consistent with the game’s style. Each biome offers its own atmosphere, vegetation density, terrain shapes, and color palettes, making every journey feel fresh and rewarding.

Whether you enjoy discovering realistic ecosystems, mysterious forests, unusual plains, or exploring deeper into beautifully crafted underground landscapes, this add-on enhances the sense of adventure and discovery—all without breaking immersion or straying from the vanilla experience.
