Spruce Trapdoor is the dark-wood variant of Minecraft's horizontal hatch, crafted from six spruce planks arranged in two rows on a crafting table to yield two trapdoors. Spruce Trapdoor opens either upward or downward, breaks fastest with an axe at a hardness of 3, and resists creeper and TNT blasts with a blast resistance of 3 (how well the block withstands creeper and TNT explosions). Spruce Trapdoor is a renewable resource, because spruce logs regenerate through saplings grown in taiga biomes, and the trapdoor waterlogs when placed inside a water source. Spruce Trapdoor responds to redstone power, opening or closing instantly the moment a signal reaches the block.

Spruce Trapdoor is a staple of taiga cabins and mountain lodges, where builders use the trapdoor as window shutters, floor hatches, fence attachments, and decorative trimming around porches. Spruce Trapdoor works as a ladder step when an open trapdoor sits directly above a ladder, letting players climb between floors without leaving a visible gap. Spruce Trapdoor is not flammable and will not catch fire from nearby flames, though direct contact with lava still ignites the block. Spruce Trapdoor was separated from the generic wooden trapdoor in Java Edition 1.13 and Bedrock Edition 1.4.0, giving the dark brown grain its own identity next to the oak, birch, and pale oak trapdoor variants.
