The Hot Air Balloon is located at the coordinates X:7392, Y:16,151, just to the south east of the Panau Capital City. All you have to do is shoot the sandbags off and you're ready to go. If you want to steer, you can simply by walking around in the basket.
You can fly the Hot Air Balloon up to 1000m, and far beyond it. You can go higher than any land point in the game, until you hit the top of the sky. Whenever you jump out, your base jump begins.
(might be a glitch)
Here's exactly what I did:
Got on top of a 747 that was taking off from the International Airport (9749, 12798), hi-jacked it in midair, flew up into the sky, pressed B to jump on top of the plane, then planted some C4 on top of the 747, pressed A to parachute, then detonated the bombs, released my parachute for a freefall, and it started counting the meters! I did a 1300 meter base jump this way.
Those are the exact steps, incase something I did made it glitch and count as a basejump!
Maybe you can go higher, I'm about to try it!
The floating club in the air.
When you go past 1000 meter (You will see it on the top left corner) open your parachute and land safely.
To perform a base jump you need to be standing near the edge of something and jump off. You need to make sure you are at a high enough point and make sure there is nothing below you that you can land on and die.
There are probably a number of different places to do this but the most common is located at the mile high club, its co-ordinates are; X: 29584 Y: 11435. You need to stand on one of the two blimps & jump off. Make sure you actually press to jump off, DON’T JUST RUN STRAIGHT OFF OF THE EDGE. For every 50 meters you fall you will see a notification at the top of the screen you need to wait until you see it show 1000 meters.
At the eastern side of the map, above a collection of smaller islands, you'll notice a double zeppelin. Work your way to the top of the zeppelins by grappling and jump down from its rear wing. You need to push to jump off, if you let yourself fall, the base jump will not trigger. Open you parachute when you pass the 1000 mark (displayed to the right of your mini-map) or alternatively, fall to your death at the 1150 mark. Both will unlock the achievement.
Note: Once you discovered the Mile High Club, you can extract to its location through the Black Market dealer, in case you failed to get the achievement.
