Want to spice up your Minecraft world? Try sending minecarts through Nether portals! It's easier than you think and opens up incredible possibilities for long-distance transportation.
The key is alignment. Make sure your portal on both sides is perfectly aligned. A single block off and your minecart (and potentially you!) will end up stuck. Place rails leading directly into and out of the portals on both sides.
For extra fun, consider using powered rails to give your cart a boost into the portal. This ensures a smooth transition, especially on longer journeys. Remember, unloaded chunks can cause problems, so keep the areas around your portal entrances loaded for optimal performance. Explore, experiment, and get ready for some seriously efficient Minecraft travel! Now, get mining and rail-riding!
