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.

Unlink Zoom between Map 1 and Map 2
Keep on the same latitude
Input the latitude and longitude of a point on the left map and see its corresponding antipode on the right map.
OR, search by place name...
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.
- 14th January 2015 - New option : Keep on the same latitude
- 19th November 2014 - Added manual input by latitude / longitude or by place name
- 9th March 2014 - Update to fix bug with crosshairs not appearing on the exact centre of the map
- 11th November 2013 - Implemented Google Maps API V3
- 21st September 2009 - Removed border around maps for better fit
- 14th January 2009 - Added Unlink Zoom option
- 22nd October 2008 - Added dual control so both maps can be the "driver" and the "passenger". The nearest country also now displays for both maps
- 22nd July 2008 - Latitude and longitude for the centre of each map is now shown. Nearest Country displayed
- 29th November 2007 - Crosshairs added to each map
- 20th September 2007 - Map 2 now starts in the correct place instead of the same location as map 1 until map 1 is moved
- 16th September 2007 - Page Created
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

I'm in Jakarta (Indonesia) and ended up on Santander Department (Colombia). Amazing
Hi, sorry, unfortunately not. It has not been developed to be downloaded or reused elsewhere.

Can I download this tool for a program I am writing?
Hi Danny, there is a new option : Keep on the same latitude

can you make it so your digging paralell to the equator? im in New Brunswick, Canada, and looks like if i dug at a bit of an angle, i actually would end up in China... and bypass that extremely hot core...ha

Strange how I get different results when I go directly to google maps and type in the same coordinates!!
I started digging from here in Weber, New Zealand and ended up in Madrid Spain!
I'm using the map to plan a future trip to Whangarie New Zealand. It is exactly opposite the Riad I stayed in while in Tangier Morocco. When I get there I'll have friends I met in Tangier place one piece of bread on the ground and I'll do the same in Whangarei. The entire earth will become a sandwich!!!

useful to know how far away from a bad marriage you can get.

This honestly made me realize how big the earth is... Awesome job.
I often use the phrase "digging to china" when asking where my kids are digging to. Nice to know it's actually the Indian Ocean near Australia that they could be digging to.

I had always hoped, as a Londoner, that Australia would be exactly 'down under' (what brought me to this website). Turns out 'down under' is actually miles away, South East of New Zealand in fact. Thank you for this illuminating tool. Well done!

No mal, yo podré llegar en el océano indiano de mi casa con...un taladro!
the main thing i found that the antipodal point lies on sea for any point on land and vice versa for almost 95 percents points. Amazing!!!!

So I just realized after tracing the perimeter of the USA in the map that it doesn't matter where in the USA you are, you'd end up in middle of the Indian Ocean (maybe if you're lucky enough you'd end up in a tiny wee island).
I live in Santiago, Chile and I'd end up in central China.

Missouri here and tunnels me to Indian Ocean. Just west of Australia 800 miles

I would find the missing Malaysia flight if I dug across the globe.

Easy to loose hours here! :D
I plan no tunnel since I'd end up close to Antarctica with Campbell Island and Pitt Island as closest strips of land.
BTW, has anybody found out which capitals line up best? I find Madrid and Wellington lining up pretty well. Quito and Kuala Lumpur being another candidate. :)
And to Pete in Bristol: Xi'an and Santiago is a good match for larger cities.

Why don't you create a map that would show a tunnel between 2 cities that doesn't go through the center of the earth, just to see the shortest distance and direction between two points through tunneling
Like inserting a pin in a city, coming out in the other one on a globe
