From the spawn just walk straight ahead or fly (if you play creative mode first). After few seconds walking or flying about 100-150 blocks and you will reach to a small lake generated on a swamp biome. Overlook it and continue your adventure, soon you will reach to the main section of this seed that is high mountain and look like the mountain is touching the sky and clouds. Surrounding area doesn’t special with huge chunks of floating islands, some open cave can be explored, and unnatural overhangs.
