We've had some interesting questions on being able to see country A from B, and on visibility for miles in every direction.

For a 6 ft tall person, the horizon in a 'flat' area is meant to be about 5km. Obviously the higher you are, the further you can see, if nothing is obscuring your view.

So somewhere on Earth (point A) presumably, you can see all the way, unobscured to Point B, which is further away than any other two visible points on earth.

Where would this line be - that is, between which two points A and B?

There's a list at this page.

COUNTRY FROM TO KM. AZIMUTH
Kyrgyzstan Dankova (5.971 m.) Hindu Tagh (6.436 m.) 538 170º
Colombia P. Cristóbal Colón (5.776 m.) Alto Mora (3.264 m.) 506 206º

Longest line of sight seems to be from Dankova to Hindu Tagh, 538 km in Kyrgyzstan. Here's a HeyWhatsThat link to the winning peaks in Kyrgyzstan/China. And another one for the combo in Colombia.
