England's longest zip wire is now operating at Honister Slate Mine in the Lake District, adding a major new adventure experience to one of Cumbria's most dramatic mountain passes.
The Honister Aerial Flight is a 1,200-metre zip wire running from Honister Crag, reaching speeds of up to 65mph. Honister says the experience took more than 20 years to bring to fruition and follows the line of the historic Lancaster Aerial Flight, which once carried slate down from the mountain.
Unlike a conventional attraction where visitors simply walk to a launch platform, this is a mountain adventure from the start. Participants first make their way up the Via Ferrata Classic, following iron rungs and steel cables on the crag before being kitted up and clipped onto the aerial line.
Here is the practical information you need before booking the Honister Aerial Flight.

What happens on the Honister Aerial Flight?
The experience begins at Honister Slate Mine, where participants are briefed and prepared for the mountain section of the activity. A guide then leads the group onto the Via Ferrata Classic ascent.
This is important when deciding whether the Aerial Flight is right for you. It is not simply a zip line reached by a lift or short staircase. You need to be comfortable taking part in the protected mountain route that leads to the launch point.
The Via Ferrata follows iron rungs and fixed steel cables across Honister Crag, using the landscape that generations of quarry workers crossed as part of their working day. The reward is a high-level launch point with extensive views over Honister Pass and the surrounding fells.
Once at the platform, Honister's guides carry out the final checks and attach participants to the aerial line. The ride itself takes around a minute, covering more than a kilometre of wire as the mountain falls away towards the mine below.
How much does the Honister zip wire cost?
Honister currently advertises Aerial Flight sessions from £109 per person. Prices and availability can vary by date, so use the live booking system before making a special journey.
This is a premium adventure activity rather than a small add-on to a mine visit. The price reflects the guided Via Ferrata ascent, specialist equipment, mountain operation and zip-wire experience.
Honister says capacity is limited during the first operating season. If the available 2026 slots sell out, further opportunities may not be released until summer 2027.
Age, height and weight restrictions
The official participation rules currently state:
- Participants must be at least 10 years old.
- Anyone aged 10 to 15 must be accompanied by a participating adult aged 18 or over.
- The minimum height is 1.3 metres.
- The maximum weight is 18 stone / 120kg, reflecting the harness specification.
These limits should be checked again when booking because adventure-activity requirements can change.
What should you wear?
Honister requires suitable strong footwear. Boots or sturdy shoes are appropriate; open-toed footwear and heels are not suitable for the mountain approach.
Specialist safety equipment is provided. The activity takes place in an exposed mountain environment, so clothing should also be suitable for Lake District conditions rather than just the forecast in Keswick or at lower level.
What happens if the weather is bad?
The Aerial Flight is weather dependent. Honister specifically warns that high winds can prevent the zip wire from operating, in which case sessions may need to be cancelled or rescheduled.
That is worth bearing in mind when building the experience into a short Lake District break. Conditions at Honister Pass can be very different from the weather in nearby towns and valleys.
Why is it called the Aerial Flight?
The name is closely tied to Honister's industrial heritage. From 1926, the Lancaster Aerial Flight carried green slate from the crag through terrain where conventional transport was difficult.
The modern 1.2km line reimagines that route for visitors while the system continues to play a role in moving slate from the mountain. That connection between working mine and adventure attraction is what makes Honister's new zip wire particularly unusual.
Is it really England's longest zip wire?
Honister describes the 1,200-metre Aerial Flight as England's longest zip wire. The company also highlights the combination of its length, high mountain setting and route over a working slate mine.
Getting to Honister Slate Mine
Honister sits high on Honister Pass between Borrowdale and Buttermere, around the western side of the Lake District from Keswick.
The mountain-road location is a major part of the appeal, but visitors should allow plenty of travel time. Roads through Borrowdale and over Honister Pass are narrow and can be slow during busy periods or poor weather.
If you are booked onto the Aerial Flight, aim to be at the site at least 30 minutes before the stated session time rather than planning to arrive at the last minute.
Can you combine it with other Honister activities?
Honister remains a working slate mine and offers a much wider programme of adventure experiences, including mine tours, Via Ferrata Classic and Xtreme, the Infinity Bridge and other climbing activities.

Is the Honister Aerial Flight worth planning a trip around?
For thrill-seekers, this is one of the most significant new Lake District adventure attractions in years. Its combination of a 1.2km flight, mountain approach, slate-mining history and Honister Pass scenery makes it very different from a conventional leisure-centre zip wire.
It is also an experience that needs planning. The price is substantial, participation rules apply, the approach involves Via Ferrata and weather can affect operations. If those factors suit your group, booking ahead is essential during the limited first season.
