Here's a great Minecraft 1.11.2 mountain seed where players start off right next to the big mountain seen above. There are some llamas up there to tame as well, not on the mountain, but up on the cliff right beside it.

The seed is: -4420372960805622199

This is a lonely mountain seed for Minecraft. There are no other mountains nearby, just this one big hill overshadowing the nearby forest. Players can see pretty far from the top of the big mountain.

This is a great Minecraft 1.11.2 seed to try out for anyone looking for mountains. While mountains aren't as exciting as they used to be in Minecraft, they're still one of the best Minecraft seeds.
