Skylands UpPort

by SmartStreamLabs

Skylands UpPort brings back the floating Skylands dimension that Minecraft once had during early development, rebuilt for modern versions.

FabricForgeNeoForgeClient and serverMIT License1.19.2 – 1.21.8

What it does

Skylands was an experimental world type introduced during the Minecraft beta period, and the mod is a reimagining of that lost dimension as a set of floating islands with forests, glowing caves and clouds below. Its terrain generation follows the peaceful, sparse style of the earliest versions, while the worldgen runs on current modern systems, so it fits the Caves & Cliffs era of terrain. The author describes it as a tribute to the game's history.

The mod is installed on the client and on the server, so both the server and every player need it. It is published for Fabric, Forge and NeoForge across seven release versions, 1.19.2 – 1.21.8, released under the MIT License but not open source. Skylands over the Sea and Aetherial Islands cover similar floating-island terrain on their own loaders.

Key features

  1. Floating island terrain

    Generates vast floating islands with lush forests, glowing caves and open sky high above the clouds.

  2. Early Skylands recreation

    Recreates the look of the Skylands dimension from Minecraft's early development, including the full classic appearance.

  3. Modern worldgen

    Keeps the calm, sparse feel of the original terrain while using modern world generation features.

  4. Portal to the dimension

    A required item turns a portal into the Skylands dimension, so players can enter the world after building it.
