This seed spawns you in the swamp next to a set of extreme hills. Nearby underground you can find an abandoned mineshaft to explore. Then not too far away in the middle of a roofed forest, you can find a village. Start by turning around and going to the cave in the middle of the trees at -9 / 61 / 203.
This seed spawns you in a taiga with a village nearby. On the opposite side of the village where you spawned, you can find a ravine with an abandoned mineshaft. In the mineshaft, there are a dungeon and a chest minecart with a diamond. This seed seems to just keep getting better the deeper you go.
This seed spawns you in a forest, but if you walk out of the trees, you can see the mesa stretched out before you. Mesas are a unique, rare biome, and spawning so close to one is a treat. Not only do they look cool with the colored clay and red sand, but they also hold a lot of great things. This one even has one diamond in a chest minecart.
The treasures of this seed all lie hidden beneath the surface except for the savanna plateau M biome. That almost acts as a bonus to the treasures.
After you spawn in the forest, head straight south into the desert. There is a desert temple buried in the sand that is easy to miss if you aren’t looking for it.
This seed is a bit of contradiction climate wise. You spawn in ice plains and ice mountains biomes, but all around the snowy areas are savannas and even a desert.
Even with how odd it may be, this seed is still awesome because it has a mineshaft down in a ravine and a temple in the desert. Those will leave you with some great items to use when exploring the different biomes of this seed.
