Highlight every Windswept Gravelly Hills patch on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Windswept Gravelly Hills are a rare, fractured mountain biome smothered almost entirely in gravel, with shattered ridges, floating islands and herds of llamas. Half of worlds have one within 2,300 blocks of the world centre. This finder highlights every Windswept Gravelly Hills patch on your seed, free, Java & Bedrock.
Windswept Gravelly Hills generate on the Overworld surface in cold, low-humidity highlands, on dramatically raised and fractured terrain of steep slopes, shattered ridges and floating islands that hang above the land. They usually border snowy plains, ice spikes, snowy taigas and regular plains, and only form where erosion and continentalness line up just right, which keeps them rare.
Usually thousands of blocks. Across 200 random worlds, half had Windswept Gravelly Hills within 2,300 blocks of the world centre (0, 0), and 9 in 10 had them within 4,900; only about one world in ten had them within 1,000 blocks. Enter your seed above and click any highlighted patch to read its coordinates. Look for the grey, gravel-coated slopes near snowy terrain; above about Y 120 the rain turns to snow and any exposed water freezes over.

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 Gravelly Hills are the colder, gravel-drowned cousin of Windswept Hills, where gravel replaces almost all of the stone, dirt and grass and leaves the slopes nearly bare (in Bedrock Edition no trees grow here at all). Many players still call this biome Gravelly Mountains, its name before the 1.18 rename. It carries the same emerald, iron and coal ore as other mountain biomes, though the gravel hides it, plus infested stone full of silverfish, and llamas roam in herds alongside cold variants of the usual farm animals.
Yes - both editions, Minecraft 26.3 on Java and 1.26.62 on Bedrock. This is a long-standing biome, renamed from Gravelly Mountains to Windswept Gravelly Hills in the 1.18 update. It runs the same world-generation maths Minecraft uses, so every patch on your seed is highlighted, free and with no sign-up.
