You spawn on a savanna beach, and the land around you is an island about 864 blocks across with water on every side. Beach is about 32 blocks away, and a mangrove swamp sits on the same island, roughly 258 blocks off. Trial chambers are about 104 blocks east, so you can start digging quickly, but the nearest village is about 491 blocks away across the water.
