Highlight every Windswept Hills patch on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Windswept Hills, long known as Extreme Hills, are the classic grass-and-stone mountains where emeralds hide in the rock and llamas roam the slopes. Half of worlds have one within 1,500 blocks of the world centre. This finder highlights every Windswept Hills patch on your seed, free, Java & Bedrock.
Windswept Hills generate on the Overworld surface as cold, jagged terrain of grass blocks and broad stretches of exposed stone, peaking around Y 140. High erosion keeps them flatter than the newer peak biomes, and above about Y 120 rain turns to snow while standing water freezes into ice. They commonly border the Windswept Forest and Windswept Gravelly Hills variants and often wrap around swamps, with plains, forests and taigas on the outer edges.
Often more than 1,000 blocks. Across 200 random worlds, half had Windswept Hills within 1,500 blocks of the world centre (0, 0), and 9 in 10 had them within 2,800. Enter your seed above and click any highlighted patch to read its coordinates, then travel there to mine emeralds out of the exposed stone and to tame llamas, keeping an eye out for silverfish hidden in infested stone below sea level.

Measured with this finder on 200 random worlds, from the centre of the world (0, 0). A seed puts its biomes in the same places on Java and Bedrock, so one column covers both. Distances are rounded.
Windswept Hills are the classic emerald biome - emerald ore generates only in mountain biomes, and these widespread hills are a good place to find it. Many players still call them Extreme Hills, the name they carried before the 1.18 rename. Llamas spawn here to tame as pack animals, scattered oak and spruce trees grow across the slopes in Java Edition (Bedrock keeps its trees in the Windswept Forest variant), and you will meet cold variants of chickens, pigs and cows suited to the chilly climate.
Yes - both editions, Minecraft 26.3 on Java and 1.26.62 on Bedrock. This is a long-standing biome, renamed from Extreme Hills to Windswept Hills in the 1.18 update. It runs the same world-generation maths Minecraft uses and highlights every patch on your seed, free and with no sign-up.
