Here’s a great seed which spawns you in a huge jungle biome. Even though there are some quite amazing hills here it’s primarily the jungle temple which is the interesting part. It takes somewhere around 30 seconds to get there (assuming that you are flying) and the unique part is that it is generated in water. It’s recommended to switch to creative when first testing this seed because otherwise there’s a risk you might get lost. Anyways, turn to your right once you’ve spawned and fly in that direction for a while.
