This is the official Bungy Nepal facebook page.

Bungy Nepal may be the most spectacular jump on the planet.At 160m high it is Nepal’s ultimate rush and one of the longest free-falls in the world.The stunning natural surroundings so close to Tibet make the jump an almost magical experience.
You can book your bungy as a day trip from Kathmandu or combine it with a stay and other activities.
On the day of your jump the jump master will first give a briefing. He then writes your weight on your hand and tells you in which group you will be jumping.
If you have any medical problems, please discuss them with the jump master.
We advise you to wear closed shoes for the bungy. Make sure your pockets are empty and know that cameras and bags are not allowed on the bridge.
We provide safety deposit boxes for your valuables.
