Enter your world seed into the interactive seed-map finder on this page to get the exact coordinates of every Jungle Pyramid in your world. From there you can travel to those X/Z coordinates in-game, or explore jungle biomes manually since temples only generate there.
Jungle Pyramids, also called Jungle Temples, generate only in the Overworld and only within jungle biomes, specifically regular jungle and bamboo jungle. They are made of cobblestone and mossy cobblestone, which helps them blend into the dense jungle foliage.
A Jungle Pyramid contains two loot chests holding items like diamonds, emeralds, iron and gold ingots, bamboo, and enchanted books. The chests are protected by a dispenser-and-tripwire arrow trap and a hidden 3-lever redstone puzzle, and no mobs spawn inside the structure.
