Hatchways
The Hatchways mod introduces special hatch-ladders into the game that open up new possibilities for movement and construction in Minecraft.
Main Features
Easy to Use - To open a hatch-ladder, simply right-click. The opened hatch ceases to be a solid obstacle, allowing free passage through it.

Flexible Placement - Hatch-ladders can be rotated in different directions, similar to logs, providing flexibility during construction and space design.

Internal Space - When the hatch-ladder is open, you can freely move through it, creating convenient passages and hidden routes.

Crafting
Creating a hatch-ladder requires only two components: 1 trapdoor and 1 barrel. The simple recipe makes this mod accessible in the early stages of the game.
