Not the biggest out there, but its the first one I found
Features:
– Right at spawn
– Village
– 3 diamonds in blacksmith chest
– HUGE mineshaft with 7 cave spider spawners +1 zombie dungeon (sadly it's not in the sulfur caves)
– Very large swamp biome around it
– Windswept gravelly hills on one side
