How to Install Oh The Biomes You'll Go for Minecraft

Minecraft·May 20, 2026·21 min read

Overview

Vanilla Minecraft worlds are built from biomes, and at first they feel huge. Deserts, forests, snowy plains, jungles, and swamps all give players different places to build, explore, and occasionally get lost in with full confidence. After enough worlds, though, the same terrain can start to feel familiar.

Oh The Biomes You'll Go, often shortened to BYG, expands world generation with many new environments, blocks, flowers, trees, and resources. It adds colorful forests, strange stone formations, flower-covered fields, icy woodlands, and plenty of new scenery for builders and explorers. This guide explains how to download BYG, install it on a Minecraft server and client, generate a new world, and recognize a few of its notable biomes.

Mod Details

BYG is owned by AOCAWOL on CurseForge, with YaBoiChips_ and Corgi_Taco credited as authors. The project has millions of downloads and supports several Minecraft versions, including releases from 1.12.2 through 1.19.2 at the time the source guide was written. Depending on the version used, it can add around 80 biomes plus related recipes, blocks, and decorative items.

Make sure the Minecraft version, Forge version, BYG file, and required dependency all match. If one piece is from a different version, Minecraft will usually complain immediately and with very little patience.

Downloading Oh The Biomes You'll Go

  1. Open the Biomes You'll Go page on CurseForge.
  2. Select Files near the top of the page to view available downloads.
  1. Find the file that matches the Minecraft and Forge version you plan to use.
  2. Click the Download button on the right side of that file.
  1. Save the `.jar` file somewhere easy to find.
  2. Download the matching TerraBlender dependency as well, if required for your selected version.

Server Installation

  1. Open your server panel and stop the Minecraft server.
  2. Check the version selector in your panel.
  1. Confirm the server is running the matching Forge version.
  2. Open the file manager or your FTP client.
  3. Find the `mods` folder. If it does not exist, create it.
  1. Upload the BYG `.jar` file and the matching TerraBlender dependency into the `mods` folder.
  2. Wait until every upload reaches 100% before leaving the page.
  1. Return to the main panel and restart the server.

Generate a Fresh World

Existing terrain will not magically turn into new BYG biomes. The mod can only generate its biomes in newly created chunks, so the cleanest option is to create a fresh world after installation.

  1. From your panel, find the world management section.
  2. Use the change world option.
  3. Enter a new world name and continue through the prompts.
  1. Restart the server so it creates the new world with BYG enabled.

You can also explore far beyond previously generated chunks in an old world, but a new world is simpler if the goal is to see BYG terrain right away.

Client Installation

Every player joining the modded server also needs BYG and its dependency installed locally.

  1. Install and run the matching Forge client version first.
  2. Open the Minecraft Launcher and go to Installations.
  1. Hover over the Forge profile and click the folder icon.
  2. In the opened directory, find or create the `mods` folder.
  3. Place the BYG `.jar` file and dependency `.jar` file inside.
  1. Return to the launcher, select the Forge profile, and press Play.

Biomes to Look For

BYG includes far more biomes than can fit neatly into one guide, but these examples show the type of variety it adds.

Autumnal Forest

The Autumnal Forest uses oak trees with green, red, and brown tones, giving the area a warm seasonal look. Tree shapes range from familiar vanilla-style forms to more uneven, custom shapes. There is plenty of wood available, but the canopy can create enough shade for hostile mobs to appear during the day.

Rose Fields

Rose Fields are open plains covered with rose-like flowers stretching across the landscape. Common passive mobs can appear here, including horses, donkeys, and foxes. This biome may also generate near Red Spruce Taiga areas, making it useful for players who want both open building space and nearby wood.

Weeping Witch Forest

The Weeping Witch Forest has a fantasy look, with large mushrooms, colorful trees, crocuses, pink anemones, and other flowers scattered across the ground. The trees can grow tall, but they are spaced far enough apart that the biome still has decent visibility and sunlight. Swamp huts and taiga villages may appear here as well.

Zelkova Forest

Zelkova Forests are dominated by tall red zelkova trees. Sheep seem especially common, and the ground is decorated with crocuses, kovan flowers, white anemones, and ferns. Because the trees rise high above the player, this biome can work well for treehouses, lookout builds, or anyone who prefers living above the problem instead of directly beside it.

Fragment Forest

Fragment Forests are defined by huge stone spires covered with oak trees, ebony trees, and tropical flowers. Water and lava springs can generate along the sides, much like they do in mountain terrain. That lava can cause forest fires if it reaches nearby leaves, so this biome is scenic but not exactly low-maintenance. It is a strong choice for elytra launches, cliff builds, or difficult climbing routes.

Frosted Taiga

The Frosted Taiga resembles a snowy taiga, but BYG gives it blue spruce trees and a colder, more distinct atmosphere. The terrain includes grass, coarse dirt, and podzol, with blueberries, irises, crocuses, and ferns growing throughout the area. Arctic foxes, wolves, and other taiga animals can spawn here.

Common Problems

New biomes are not showing up: You may have spawned in a vanilla biome, so travel around before assuming the mod failed. If the server was using an existing world before BYG was installed, generate a new world or explore brand-new chunks. From your panel, use the world change option, enter a unique world name, then restart the server.

The game crashes or shows an error: Check that Forge, BYG, Minecraft, and TerraBlender all match the same supported version. Install the dependency on both the server and each client. After correcting the files, restart the server and relaunch Minecraft before trying again.
