You spawn in a jungle biome with a large desert ahead. In the distance there is an NPC village, we will start there. The coordinates for this village are X: 55 Y: 105 Z: 166. There is no blacksmith here but there are some nice desert mountains in the background. In addition, visible from this location, there is a desert temple slightly sunk in the sand. The coordinates for the temple are X: 26 Y: 74 Z: 297.
Near the spawn point a jungle and swamp biome intersect. If you trace the path of intersection you will eventually come across a jungle temple at X: -362 Y: 69 Z: 118
There is a surface dungeon with an enchanted book in it at X: 156 Y: 69: Z: -63…this is very close to the second village which does have a blacksmith this time. There is also a second desert temple at X: 360 Y: 73 Z: -149.
If you dig down vertically at X: 766 Z: -99 there is a stronghold below. There is a zombie spawner in the stronghold and it is has the enchanted book fortune 3 in it. I found surface diamonds and emeralds surrounding the stronghold, so if you explore for a bit you will find them as well.

This Minecraft Seed spawns you in a plains biome with a half dozen cows nearby. Also, next to the spawn point is a decent cave system which will make gathering some ores very easy at the start. So grab some coal and iron ores and lets move on. (X: 11, Z: 133 for a dozen surface coal ores…torch time!)
There is a small NPC town at X: 83 Z: -154. It comes complete with a blacksmith and several farm animals (cows, sheep) nearby. It is in the plains with a jungle biome near. There is a ravine really close to here at X: -15 Z: -232. In a cave near the bottom of the crevice is an abandoned mineshaft and in there are several surface diamonds at X: -1 Y: 14 Z: -165. If you keep exploring you will find 2 more diamonds at X: 26 Y: 13 Z: -165
There is an absolutely ridiculous ravine that you MUST go check out. Its double wide with a lava floor. Surface diamonds all over the place and an abandoned mineshaft. X: -683 Y: 17 Z: -199. There is a stronghold connected to the abandoned mineshaft, if you have the coordinates for it leave them in the comments. Check out the video:
There is also a Jungle Temple (X: 878 Y: 78 Z: -384) and Desert Temple.
