England's last working slate mine sits at the top of Honister Pass — and since August 2026 it's also home to England's longest zip wire. Here's what's actually there, what it costs, and what the Aerial Flight really buys you — because it isn't a sixty-second ride.
Opened 4 August 2026
The Honister Aerial Flight opened on 4 August 2026 after more than fifteen years in development. It runs 1,200 metres — 1.2 km from Honister Crag, launching from roughly 2,000 ft above sea level, down across the head of the pass to the visitor centre. Riders reach speeds of up to 65 mph.
The name is doing deliberate work. From 1926, an aerial ropeway called the Lancaster Aerial Flight carried Westmorland Green Slate down from the crag, through the air, where no cart could go. The new ride is the Honister Aerial Flight — the same idea, a century on, along broadly the same line.
And it is still dual-purpose: it carries slate down the mountain as well as people. That is the part worth holding on to. It isn't a theme-park ride bolted onto a hillside — it does a job, just as its predecessor did.
Age, height and weight limits published by Honister, checked August 2026. They describe the weight limit as a harness specification. Limits differ by activity — confirm when booking.
Honister's page shows the Aerial Flight at from £109 per person (checked August 2026) — "from", so treat £109 as the lowest price displayed rather than a single fixed fare. They also describe first riders as paying a founder-season rate, which suggests it won't stay at this level.
The important part: you are not paying £109 for a sixty-second ride. The flight is the way down. To get to the launch point you climb the Via Ferrata Classic — the old miners' path, on iron rungs and steel cables, with a guide. The zip is the last minute of a half-day on the mountain, not the whole product.
Set against the rest of the price list, that reads as fair rather than steep. The Via Ferrata Classic on its own is from £55; the Xtreme is from £70. So £109 buys you the Classic climb plus a 1,200 m descent off the top — roughly £54 on top of a climb you would otherwise pay £55 for. Whether that particular minute is worth £54 to you is a personal question, and one we'll answer properly once we've ridden it ourselves.
This is the single thing most people don't realise, and it changes the whole shape of the day. There is no lift and no minibus to the launch platform. You get there by climbing the Via Ferrata Classic — the route Honister already sells as an activity in its own right — following the old miners' path up the crag on iron rungs and steel cables, roped to a guide the whole way.
So the honest description of the Aerial Flight is not "a sixty-second zip wire". It is a guided via ferrata ascent with a 1,200 m flight as the way back down. Anyone picturing a point-and-go ride where you queue, clip on and step off has the wrong idea entirely.
What that means for who can do it. It is not primarily a fitness test — the Classic is graded for first-timers and takes most reasonably fit adults and older children comfortably. What it does demand is a head for heights. You are on an exposed rock face with a lot of air beneath you for a sustained period before you ever reach the wire, and the exposure is continuous rather than a single moment you can brace for. People who are fine on a ladder and not fine on a cliff edge should be honest with themselves about that in advance rather than discovering it halfway up.
Practically: arrive 30 minutes before your slot to kit up, get fitted and meet your guide, and treat the whole thing as a substantial part of a day rather than a stop on the way to somewhere else.
Before you go
Everything adventurous at Honister is ticketed and guided. Honister says it does allow on-site ticket purchases but recommends booking in advance, particularly in peak season — and for the Aerial Flight specifically there is a harder limit than "it gets busy", which is worth understanding before you drive over.
The planning permission for the Aerial Flight caps it at a maximum of 57 riders per day. That is a condition of consent, not a commercial decision Honister could reverse if demand is high — the ceiling is set by the permission itself.
It explains the scarcity far better than the usual "places are limited" line. Fifty-seven people a day is not many for an attraction with this much attention on it, and Honister's own booking page describes this as a limited first season, opening summer 2026, with the next chance being the following summer once the slots have gone. If you have a specific date in mind, book it.
We don't sell tickets and we're not a reseller — book with Honister directly, where you'll also get current prices, age and height limits, and season dates. Book at honister.com
You're going to 2,000 ft, in any season. Waterproofs, gloves and sturdy footwear — and note the operator's rule: no heeled boots and no open-toed shoes. It's routinely colder and windier at the top of the pass than it is in Keswick.
Ask your guide on the day. Mounted devices may be permitted while handheld ones aren't, but we're not going to present that as settled policy — it's the kind of thing that varies by activity and conditions. Check when you book.
The planning application for the Aerial Flight described a powered cable climbing trolley, and said the flight would be available to visitors with restricted mobility and to children under 10 by that means.
Read that as what was proposed and approved on paper, not as what is on offer today. We have not confirmed that the trolley is operating, or that either group can currently book, and we are not going to imply otherwise from a planning document. It is also not an age policy. Honister's own published minimum for the Aerial Flight is age 10 (see the limits above); any provision for younger or less mobile riders is Honister's to confirm, and not something to infer from a planning document. If this matters to your booking, ask them directly before you travel.

Getting there
Honister Slate Mine sits at the summit of Honister Pass, on the B5289 between Borrowdale and Buttermere — postcode CA12 5XN. From Keswick it's roughly 25 minutes south through the Borrowdale valley, and the drive itself is one of the finest in England.
There is a car park at the mine. Honister lists parking as a separate paid item rather than bundling it with activities — we didn't capture a price in our August 2026 check, so budget for it and confirm on the day.
Honister's own FAQ says there is "ample parking on site". Worth knowing alongside that: the car park does double duty — it's also the highest-starting access point for Haystacks, Great Gable and Fleetwith Pike, so it serves walkers as well as visitors to the mine. If you're only walking, be aware you're parking at a commercial attraction with its own charges, not a roadside lay-by.
The pass itself — the gradient, the hairpins, winter closures and whether to take a motorhome over — is a subject of its own: see our guide to driving Honister Pass.

Honister's via ferrata was England's first, established by Mark Weir on the historic miners' path up Fleetwith Pike. The Classic follows the old route on fixed iron cable; the Xtreme adds overhangs, a Burma Bridge and the Sky Ladder. Both are guided, and you're clipped to a continuous safety cable throughout.
A full guide to what via ferrata actually involves — and whether it's for you — is on its way.
A high wire bridge strung 1,000 ft above the valley, which Honister describes as Europe's longest of its kind. We're repeating the operator's claim there rather than making it ourselves — but it is, by any measure, a long way up.
Getting the claim right
This gets muddled constantly, including in places that ought to know better, so here it is plainly.
At 1,200 m, the Honister Aerial Flight is the longest zip wire in England. That claim stands.
Zip World's Velocity 2 at Penrhyn Quarry in North Wales is longer, and is generally described as the longest in Europe. Wales is part of the United Kingdom but is not part of England — so "England's longest" is accurate and "the UK's longest" is not. If you see Honister described as Britain's or Europe's longest, that's an error, and it's one we're not going to repeat just because it sounds better.
There's also a separate question people ask — the longest in the Lake District. Honister holds that comfortably. The other well-known Lakes operation, Zip World Windermere, is a very different proposition: forest-canopy zip lines rather than a single 1.2 km run off a mountain. If you want length and altitude, Honister. If you want a woodland adventure course closer to Windermere, that's the other one.
The working mine
Honister is England's last working slate mine. The stone is Westmorland Green Slate — the distinctive green-grey slate you'll see on roofs and walls across Cumbria and in a good deal of high-end building work well beyond it. This is the point that's easy to miss among the zip wires: the mine is a going concern, not a heritage exhibit with a gift shop attached.
The site's modern history turns on Mark Weir, who bought the mine and reopened it — the Aerial Flight's opening fell 30 years after that purchase. He established England's first via ferrata here, on the old miners' path.
Mark Weir died on 8 March 2011, aged 45, when his Gazelle helicopter crashed shortly after taking off from the mine. An inquest in 2013 returned a conclusion of accidental death. The mine is now run by his sons, Prentice and Piers Wilkinson Weir.
The Aerial Flight took more than fifteen years to get off the ground, and the delay was planning rather than engineering. An early application was refused. Consent was granted by the Lake District National Park Authority in November 2018, upheld by the Secretary of State in 2019, and then re-approved in 2025 after changes to the landing-post arrangements.
Friends of the Lake District objected, on grounds of landscape impact, tranquillity, noise and biodiversity, and Buttermere Parish Council objected alongside them. That is a serious conservation body and the elected voice of the valley on the receiving end, both making a case about what a National Park is for — and the fact that consent was eventually granted doesn't make either objection frivolous. Equally, the mine is a working industrial site in a valley shaped by two centuries of quarrying, and the wire carries slate as well as people. Both of those things are true at once, and we'll leave readers to weigh them.
On foot from the top
The mine car park is the highest road access in this corner of the Lakes, which makes it the least-climbing start for several big fells. Note that you're parking at a paid attraction, not a free fell car park.
The easiest way up Wainwright's favourite — start high, follow the old tramway past Dubs Quarry and the Drum House.
The least total ascent of the three main routes, crossing Grey Knotts and Brandreth. Still a real mountain day.
Fleetwith Pike rises straight above the pass — the via ferrata climbs its miners' path. Routes from Gatesgarth and Buttermere.
Common questions
