Straight ahead of you from spawn is the huge mountains located in a savannah biome. It is literally huge and extreme with multiple overhangs and really cool hills, valleys and beautiful rivers.

Across the seed there are multiple exposed caves and dungeons. With exposed we mean that you can get straight into the caves and dungeons without having to mine your way through any blocks. It's right there in the open just waiting for you to explore it.

It's a huge seed and would take at least an hour to discover just this part of it wholly. By just poring over it for a few seconds you can make really cool findings, such as the lava flowing out of the mountain and into the riverbed.
