Introduction
Usually when people have outposts in other biomes, they travel there via Minecart.

But by using math, you can get there via Nether Portal!

Materials
20 Obsidian

A flint and steel

And These Facts
X- Increases East, decreases West.

Y- Increases by height, decreases by depth.

Z- Increases South, decreases North.

You can relocate Portals in the nether using a little math

Steps
1. Nether portal. If you don't have one, make one.

2. Find your desired location you want to travel to.

3. Note the coordinates of the area, then divide the X and Z values by 8 (by 3 if playing the Console Edition). You can ignore the Y value.

4. Go through your portal & head to those divided coordinates. Try to place yourself at about the same elevation, then make your portal. You should come out about where you were previously.

Note: This works because one block in the nether is equal to eight block in the over world. For example, to travel 800 blocks in the over world, you would only need to travel 100 blocks in the nether.
