Tunnel to the Other Side of the Earth

Have you ever wondered which part of the other side of the earth is directly below you? Find out using this map tunnelling tool.

How to use the Map Tunnelling Tool

Drag map 1 or 2 by clicking and holding the map as you move it. When you let go and finish dragging the map the other map will then show you where about's on the earth the far end of the imaginary tunnel will be. In effect it will show you what is at the other side of the earth.

To make things easier, you can also zoom the map in and out.

You can adjust the height of the map by using the small, medium and large buttons.

You can also change the map view using the Map, Satellite and Hybrid buttons. This works independently for each map.


This is a Antipodes Map. An antipode of a point on the earth is the region on the Earth's surface which is diametrically opposite to that point. The two points which are antipodal to one another are considered to be connected by a straight line or tunnel through the centre of the Earth.

Future Developments

Ideas and improvements that are due to be implemented in the future. If you think of any ways of improving this tunnelling tool or spot any bugs, then please get in touch.

  • Measure distance between the two points in question to discover the length of the tunnel (request by Baker)
  • KML download for each of the two points for use in Google Earth

What would happen if I drilled a tunnel through the centre of the Earth and jumped into it?

It's interesting how little of the populated world actually overlaps. Pretty much only Argentina and Indonesia.
