Urban canals have long been rediscovered as quaint, idiosyncratic backwaters for boat dwellers, joggers and cycle commuters, or have seen adjacent industrial wasteland redeveloped into glitzy apartment blocks or waterside business parks complete with mouth-watering eateries and amusing sculptures. The old cliche of filthy neglected ditches where joy-riders dumped scooters and drunks hurled traffic cones or shopping trollies is outdated, at least in central London.

These days, if Doctor Who needs a grotty urban canal to stand in for a toxic sewer where evil Cybermen are spawning The Invasion (1968; 00.57), they’d probably have to go abroad or something. All of which means that, once you include London’s excellent transport links, the capital’s fascinating canals make for great packboating.

The 200-year old Regent’s Canal is inner London’s best example, arcing nearly 9 miles across London from near Paddington eastwards to the old docks at Limehouse on the Thames. It starts at the dreamy, willow-rimmed mooring of Little Venice, passing Regents Park’s neoclassical mansions and the chattering apes of London Zoo before turning for Camden Lock Market where Jimi Hendrix bought his first Rosetti Airstream. Here the canal drops down a few locks to unrecognisably redeveloped Kings Cross, home of Google UK and where giant Victorian-era storage tanks have been converted into luxury flats. East of here, your water-level view flits between bohemian, suburban, light industrial and even rural parkland, until you arrive at the marina of Limehouse Basin by the Thames. On the way you’ll have portaged 13 locks and two tunnels (marked in red on the map below).

The Regent’s Canal

Britain’s canals helped kick off the world’s first industrial revolution. Canals linked or added to long-established river navigations and enabled inexpensive and reliable cross-country transportation of heavy, bulky or fragile commodities, like pottery. At this time the decrepit road network was still suffering from 1500-years of neglect following the Roman era. Packhorse trains were superior to wheeled carts but were way too costly.
Around 1805 the Grand Union Canal linked the burgeoning industrial heartlands of the Midlands with Paddington – then a village on the western edge of London. The advent of Napoleonic Wars included attacks on coastal shipping, necessitating secure inland transportation to help provision the war effort. (The Wey-Arun Navigation linking London with the navy fleet at Portsmouth, was another example).
The Regent’s Canal followed London’s northern perimeter to link the Grand Union with the deep tidal Thames at Limehouse (above) near the new West India Docks. Here, lock-controlled ‘wet docks’ were regarded as more efficient and secure than London’s old bankside wharves. The map below is from 1830 and shows that even a decade after the canal opened, most of it passed through open countryside. Within a few decades railways gradually brought about the demise of commercial canal transportation. 
I pinched most of this information from Jack Whitehead’s detailed version.

The canal ahead of the lifting Fan Footbridge is cordoned off so you can’t actually put in here. Along with the similar ‘Curling‘ Bridge nearby, a cynic might say these are eye-catching engineering solutions to non-existent problems while other celebrate innovative urban art. Both bridges make scheduled performances on weekends.

The Paddington Arm of the Grand Union. Regents Canal actually starts by the former barge turning-point known as Brownings Pool; today’s Little Venice.

Just up the way below a footbridge is a strange retracting weir whose purpose may be to keep the scourge of duckweed from spoiling Paddington Basin’s clear-water vibe.

You can put in anywhere around here but…

Maida Hill Tunnel
Before you start assembling your boat, know that in about 5 minutes you’ll need to backtrack from and portage around the 250-metre-long Maida Hill Tunnel which is closed to ‘non-powered craft’. And it’s not a quick 250-m hop-around either. Because of a private towpath along Blomfield Road, and closures for repairs, currently it’s nearly a mile before you re-access the water below the Casey Street footbridge east of Lisson Grove. Knowing this, you may prefer to do as I did, and walk to (or start from) Casey Street Footbridge, about half a mile north of Marylebone tube. See map below.

The temporary towpath closures (left) are to repair electric cables stemming from the power station at the end of Aberdeen Place at the tunnel’s eastern end. When it reopens the portage distance will halve, but that may be a while.
So, you can paddle up to the western tunnel entrance from the Little Venice end (paddleboarder, below left), but you can’t get out here onto Blomfield Road because of a locked gate to the moorings. You have to backtrack to Little Venice, but it’s probably still worth it for a peep into the short if forbidden void.

In 2018 the Canal & Rivers Trust (formerly British Waterways) provisionally opened the 250-metre-long tunnel to paddle-powered craft. (Consultation document.) According to their own regs, any straight canal tunnel of less than 400m can be paddled. At Maida Hill you can clearly see the other end, anything coming at you will be silhouetted or lit, and the whole drama takes a couple of minutes to paddle, including taking pictures.

But to saves costs the tunnel is narrow and without a towpath (barges were legged through by ‘walking’ off the walls). Passing isn’t allowed or even possible, even in a slim kayak. Or a boat operator may not notice low-in-the-water kayaks, even with the mandatory headlight. Tour boats run via the tunnel daily from 10am between Camden and Little Venice.

‘Thank you for your enquiry. We do not allow kayaks through the Maida tunnel unless it is part of a special event”.
Three months notice is preferred for your special event and solo transits are not allowed anyway.
The website additionally warns:
Non–approved unpowered craft shall not transit the tunnel eg. rafts and other types including inflatable arrangements designated for ‘fun’ use.

Clearly, they’re no more clued-up about modern IKs and packrafts than the BCU, or assume we’re all intoxicated pillocks goofing about on inflatable unicorns.

What could possibly befall a typically open and unsinkable IK, canoe, packraft or iSUP board in the tunnel? Do they assume such boats are inherently more dangerous than a beginner capsizing mid-tunnel in a tippy hardshell?
Maybe the CRT has had problems with ‘inflatable arrangements’. Who knows, but I’ve also encountered this anti-inflatable prejudice on PLA media about padding the tidal Thames. I suppose it’s too much to expect these officials to know the difference between an Intex bin bag and a €3000 Grabner, but the common denominator must surely be the required BCU licence (or a more expensive and limited pass direct from the CRT). I wouldn’t be surprised if it’s a canalised version of road-tax paying car drivers [cruise operators] vs freeloading pushbikes [kayakers]. The resentment the former feels towards the vulnerability of the latter generates irritation.

Here’s a suggestion: mount some traffic lights at each end on a 5-minute turnaround, and perhaps some low-level motion-activated illumination inside. That way the Maida Hill Tunnel could be safely and easily open to all users. Apparently, it’s currently being considered.

Long story shortened a bit, I enjoyed my exploratory walk and finally got to air-up my MRS Nomad below Casey Street footbridge looking down on the Lisson Grove Mooring (aka Marylebone Wide).

The canal surface was thick with a lush carpet of floating pennywort or, as I prefer to call it, Hydrocotyle ranunculoides. This lurid green matting covered the canal from bank to bank just about the way to Limehouse. At times it was so thick birds easily stood on it, but it didn’t noticeably impede my paddling…

… because an MRS Nomad doesn’t exactly slice through water like Poseidon’s scythe. Once on the water I paddled back west, under the Lisson Grove or Eyre’s ‘tunnel’…

… for a peek at the eastern, ‘Doctor Who’, end of the Maida Hill tunnel. It didn’t look that far or that deadly. Then I paddled back, passing nesting coots…

… and preening fowl. By 8am I was on my way to Limehouse.

Under the Chiltern Line rail bridges and Park Road (A41).

And into the bucolic enclave of Regent’s Park, passing elegant mansions and accompanied by a phalanx of pushbikers and joggers dashing and dodging other joggers and pram-pushing nannies.

At London Zoo all was quiet. Not a squawk, a yelp or a roar.

Regents Park was built around the same time as the canal, and one reason the canal didn’t simply cut directly east from Paddington towards the City along today’s A501 Marylebone Road (called ‘New Road’ back then, blue below) is because the well-connected park developer objected under the Tudor Statutes of NIMBY. The dirty canal diggers were forced to burrow like badgers through Maida Hill before swinging off on a northerly arc, all adding hugely to the cost and completion time. Funding the canal was a real stuggle. 

At now-filled in Cumberland Basin (red, above), by the famously top-heavy Chinese pagoda restaurant the canal, appropriately, takes a left turn into the borough of Camden.
Soon I arrive at Camden Lock Market but it’s too early on a weekday morning for the place to be busy with beret-wearing tourists.

There are three locks here in less than 300 metres, so I line the boat along the bank like a Yukon voyageur.
I paddle away from trendy Camden and soon pass under the deafening Eurostar rail lines at St Pancras before entering what they now call Gasholder Park. Old Kings Cross is long gone and some of the gas storage tanks have been turned into flats. Welcome to trendy Kings Cross.

In the Eighties when I squatted near here, ‘trendy’ + ‘Kings Cross’ were not recognised combination. This was probably the seediest corner of central London and the real thing with junkies, prostitution and porno studios – a far cry from quaint, touristy Soho.
One time we used the gas tanks as a backdrop for an article I’d written about a motorbike running on Nitrous Oxide or laughing gas. Fans of Mad Max will know about that. Mike Leigh’s High Hopes (1988) was filmed around the corner. Funnily enough, the story was about a lefty-slacker moto messenger, his woebegone mum and some pantomime-vile yuppies. Oh happy days!

A lifeboat houseboat. No worries about rising sea level or tsunamis here.

The Word on the Water floating bookshop. I can’t quite square where I am with what lies around. I think back in my day it was all once a huge goods yard behind high walls. I swing into Battlebridge Basin but the museum isn’t open yet.

Up ahead is the 880-metre-long, Islington Tunnel. Again, as straight as a broomstick but closed to hand-powered boaters for similar reasons as Maida Hill. I was kind of hoping a barge might rock up and let me hook on for a lift, but the only things I’ve seen on the water are wildfowl, plastic bottles and Spirodela polyrhiza. The museum organises  boat tours through the tunnel two days a week. Maybe they’d agree to some slipstreaming.

I read that the portage follows helpful plaques set in the pavement. Cross the A1, Upper Street and head for Duncan St. It’s about a kilometre and would be somewhat of an arseache in a hardshell. Either way, I emerge at the eastern portal…

… and in need of a waterside snack at City Road Lock. It’s only 9.30.

By 10am I’m refreshed and on the move again. I put back in below the lock with a plop.

The canal turns north into Haggerston where, just after the Whitmore Road bridge, there’s a handy knot of cafes on the left. A better choice than City Lock if you want more than coffee and cake. It’s all yummy mummies round here, not the snarling, bottle-throwing punks I’d feared.

Kingsland Basin to the north, with a somewhat baffling kayak slalom course. Soon you pass under the Kingsland Road bridge, edging ever closer to south Hackney. or ‘Acne’ as some call it.

The canal is actually about 4 feet deep. near here I can see traffic cones and other junk on the bottom. But a prod with the paddle reveals two centuries of anaerobic silt, so don’t expect to be able to stand if you fall in.

A populist ambush. These Eastenders are such wags.

Swan narcissus. There’s a fairy tale in there somewhere, a swan that fell in love with its image and was turned into an ugly duckling.

Another trickling spillway below a lock. I’ve lost track where.

Nosferatu guarding someone’s tent. Sure beats a shopfront on the Strand.

More gas holders near Cambridge Heath Road. You always find them near canals as the huge tanks need to float on water.

They’re actually like an upside-down cup resting buoyant on water and are as much about producing an even pressure as storage. Gas from a nearby factory is pumped in to the cavity above the water depending on demand, and the weight of the lid keeps the low pressure steady as it’s released out into the network (in an era before regulators).

New graffiti; 28-speed revolutions.

It’s that Nosferatu again. You just can’t get rid of him.

I’m approaching Victoria Park near Bethnal Green or South Hackney, it’s hard to tell. The precise name of your neighbourhood is very important to Londonders.

By Old Ford Lock (named after a car they dredged out of the canal in 1981) are the first canalside public toilets I’ve seen. Good to know. A nutty, bin-rummaging vagabond in a top hat has a quick chat and warns me of heavy weed ahead.

Is that a real turtle on the sunken kayak or a rubbery Hacknean joke?

On the left the Hereford Union which leads two clicks up to the Olympic Park and the River Lee Navigation. We’ll be exploring there shortly.

More of yer Acne ‘umour?  Someone report these ratbags to the CRT, pronto! You won’t see such frivolity in la-di-da Little Venice.

Architecture-spotting: new, old, industrial, domestic, elegant, ugly – is all part of the fun on the Regents.

I probe a weed-clad lock. Locks are creepy places.

Canary Wharf ahead – the former Docklands of London which was the Regents’ very raison d’etre.

And here we are at Limehouse Basin and the first actual moving boat I’ve seen since Paddington.

A lot of weed to clean off.

All wiped down and rolled up.

I set off to walk upstream along the Thames for a bit.

The river looks really quite choppy and a strong spring tide shoves an abandoned kayak upstream towards Wapping.

Bored [sic] as a coot? Not on the Regents Canal!

Thanks for reading.
