So, you want to go fast. Not just "car on a highway" fast, but "strapped to a wire over a canyon with nothing but a helmet and some prayer" fast. Most people think all ziplines are basically the same—you climb a tower, you zip down a cable, you have a nice view.
Honestly? Most ziplines are slow. They’re built for tourists who want to see the trees. But there is a tiny, terrifying group of fastest ziplines in the world that are engineered specifically to break speed limits. We are talking about hitting triple digits in miles per hour.
If you’re looking for a leisurely glide through the rainforest, this isn’t it. This is about G-forces, eye-watering wind, and the kind of speed that makes your stomach feel like it’s staying at the launch pad while your body is already half a mile away.

The Absolute Speed King: Tirolina Ordesa Pirineos
For a long time, there was a lot of debate about which wire was actually the fastest. You had people pointing at Wales, others looking at South Africa. But in June 2021, a spot in the Spanish Pyrenees basically ended the argument.
Tirolina Ordesa Pirineos officially clocked a record speed of 117.4 mph (189 km/h).
It’s located right at the edge of the Ordesa National Park. The drop is massive—about a 400-meter vertical difference from start to finish. Because of the way the mountains are shaped there, the wind often acts like a literal turbocharger. You aren’t just falling; you’re being propelled.
The most wild part? Most people don't even know it exists. They go to the bigger tourist hubs and miss out on the actual world-record holder. If you want the peak of "fast," this is the mountain you have to climb.
The Famous One: Zip World Velocity 2
If you’ve ever watched a viral video of someone screaming their head off over a bright blue lake in a quarry, you’ve seen Velocity 2. It’s tucked away in the Penrhyn Slate Quarry in North Wales.
For years, this was the undisputed champ. It’s still the fastest zipline in Europe and arguably the most famous one on the planet. You lie face-down in a "superhero" position, which sounds cool until you’re actually looking 500 feet straight down at the water.
- Top Speed: Regularly exceeds 100 mph (160 km/h).
- The Vibe: It feels industrial. You’re flying over an old slate mine, which gives it a gritty, high-stakes atmosphere.
- The Catch: You have to do a "little" zipline first to prove you won't pass out. It’s a smart move by the operators, honestly.
The acceleration here is what gets you. It doesn’t gradually build up; you just drop, and suddenly the wind is trying to peel your goggles off.
The Middle Eastern Giant: Jais Flight
Ras Al Khaimah in the UAE doesn't do anything small. They decided to build the longest zipline in the world, the Jais Flight, and in the process, they created one of the fastest.

It’s nearly 2 miles long. That’s roughly 28 football fields. Because the cable is so long, you have a lot of time to build up momentum. You’ll hit speeds of around 93 to 99 mph (150-160 km/h) depending on your weight and the wind.
You start at the peak of Jebel Jais, which is the highest point in the Emirates. It’s a weirdly silent experience at first because you’re so high up that there’s no ground nearby to give you a sense of scale. Then, you pass a cliff edge, and the world just disappears.
You eventually land on a suspended platform that hangs in the middle of the air. You then have to take a second zipline to get back to solid ground. It’s basically an adrenaline sandwich.
The Old Guard: Zip 2000 in Sun City
We can’t talk about the fastest ziplines in the world without mentioning the one in South Africa. Zip 2000 was the pioneer. It opened in 2004 and held the world record for over six years.
It’s located in Sun City, and while the newer tech in Spain and Wales has technically overtaken it in "official" record books, some riders swear they’ve hit higher speeds here. There are unconfirmed reports of people hitting 115 mph (185 km/h) on this line during particularly windy days.
The design is unique because it uses a "primary" and "secondary" braking system that allows for a much steeper initial drop than your average canopy tour. It’s 2 kilometers of pure, unadulterated speed.
Why Speed Isn't Just About the Cable
Most people assume that if you put a wire on a hill, you’ll go fast. Sorta true, but not really. The speed of a zipline is a math problem involving gravity, friction, and "frontal area" (that’s you).
If you want to go faster, you want to be "heavy and small." This is why many of these high-speed lines require you to wear a specific suit or lie flat. Sitting in a harness creates too much drag. You’re basically a human parachute. By lying flat, you cut through the air like a dart.
Factors that actually change your speed:
- Your Weight: Heavier riders actually go faster because they have more momentum to overcome the air resistance. If you’re on the lighter side, don't be surprised if the guy behind you clocks a higher speed.
- The Wind: A headwind can shave 20 mph off your top speed. A tailwind? That’s how records are broken.
- Cable Tension: A tighter cable means less "sag." Less sag means you don't lose energy moving the cable up and down, keeping all that energy moving forward.
What to Actually Expect (The Scary Parts)
If you’re planning to hit one of these, there are a few things nobody tells you.
First, it’s loud. When you’re moving at 100 mph, the wind isn't a "breeze." It’s a roar. It sounds like a jet engine is right next to your ear.
Second, the "stop" is often more intense than the "go." These lines use complex braking systems—sometimes magnets, sometimes huge springs. Going from 100 mph to zero in a few seconds is a massive rush, but it can be a bit jarring.
Third, your eyes will water. Even with goggles, the sheer pressure of the air tends to make your face do weird things. If you’re wearing a GoPro, the footage will likely be 50% you looking like a confused bulldog.
Actionable Tips for Your First High-Speed Zip
If you're ready to book a trip to Wales or Spain, keep these things in mind so you don't waste your money or get turned away.
- Check the Weight Limits: These aren't suggestions. High-speed lines have very strict minimum and maximum weights (usually between 40kg and 120kg). If you’re too light, you might not make it to the end. If you’re too heavy, the braking system might not be rated for you.
- Dress for the Wind: It might be 75 degrees at the bottom, but at 100 mph at the top of a mountain, it feels like freezing. Wear tight-fitting clothes. Anything baggy will flap around and hurt your skin.
- Book the Morning: Wind usually picks up in the afternoon. If you want the smoothest, fastest ride, the first slots of the day are usually your best bet.
- Look at the Horizon: People tend to look down at their feet. This makes you dizzy. If you look at the horizon, you get a much better sense of the incredible speed you're actually traveling.
Getting onto the fastest ziplines in the world is a bucket-list item that actually lives up to the hype. It’s one of the few ways a regular person can experience those kinds of speeds without being inside a vehicle. Just remember to breathe—if the wind lets you.
To get started, your best bet is to look into Tirolina Ordesa Pirineos for the pure speed record or Zip World Velocity 2 if you want the most established, professionally polished experience. Both require bookings weeks in advance, especially during the summer months.
