I have no coordinates to give you directions so I will try and reference the spawn point. Here is a screenshot from the spawn point:
Giant lavafall, mountains, and
lots of different biomes. There is a good reason nyan is the most popular minecraft pe seed. Lets keep moving.
Here is a screenshot of the spawn point from a distance, note the two lava falls and waterfall as well as the massive mountain range:
Here is a shot of the backside of the mountain range, yet another lavafall and waterfall. Absolutely stunning! This seed for minecraft pe is a winner!
Around that side of the mountain is this huge cavern into the side of it, time to explore!
Its a dead end, but start mining and let me know what you find.
