A ride down the tide on the Sound of Jura
As we moved out from the Gulf of Corryvreckan into the Sound of Jura the tidal stream was increasing and our GPS confirmed that feeling. Pretty soon we were travelling south at 10 Kph with very little paddling effort.
At the very end of the trip and the end of a lengthy day of paddling, this was a pleasant way to travel! We headed across towards the mainland side of the Sound, taking transits as we went to make sure we passed to the east of Ruadh Sgeir (Red Skerry), a small island in mid channel which splits the tidal stream.
As we approached, the true speed of the flow became apparent and we were slung around the north of the island at a terrific rate........
....into flat calm water - but even here we were getting a great ride down the tide. The view down the Sound to the distant Paps of Jura under a huge cloudscape was very fine.
We passed inside Carsaig Island into a lagoon reflecting the blue of the sky and the vivid green of early summer vegetation.
A familiar yacht was anchored in Carsaig Bay - we'd last met with "Wild Rose" on the west coast of Iona - and she looked just as good in her home bay!
The last few hundred metres into Carsaig seemed to pass quite slowly, we were out of the tidal assistance and we were all tired at the end of a long day.
David and Maurice were heading home the same due to work commitments while Douglas, Sam and I had intended to stay on the water and paddle a little way south to find a wild camp for the night. In the event, we elected to join David and Maurice for dinner at the Tayvallich Inn - which we can heartily recommend - we ordered identical meals - fish and chips all round! From the Inn it was just a few metres to the Tayvallich camp site which we three stayed on for the night.
What a trip it had been! We paddled 135 Km over four days and camped for three nights on some of the wildest and most remote beaches on Scotland's west coast.
A second trip to Jura in two years just reinforced my view that it's amongst the very best of sea kayaking destinations - wild scenery, wildlife, remoteness, grandeur and fast tidal streams make for a potent mix. Colonsay and Oronsay exceeded the very high hopes I had - this was my first visit to both those islands and it most certainly won't be the last.
As ever though, it's the people who really make trips special. To David, Maurice, Sam and Douglas - thank you so much - and Slainte!

All in the timing at the Gulf of Corryvreckan
As we paddled out from Glengarrisdale towards the north tip of Jura and the Gulf of Corryvreckan, a narrow strip of clear sky broke the uniform grey of the cloud cover; and seemed to point the way to the Corryvreckan.
The island of Scarba gradually emerged as we neared the strait, the sky continued to clear and the temperature soared. Most of us found tiny bays to land in to remove layers of clothing!
The scale of the west coast of Jura is impressive, and certainly this northern section doesn't disappoint - our kayaks were dwarfed by the outcrops of tilted rock layers.
We had timed our arrival at this critical point of our journey to take advantage of the brief period of slack water at the end of the flood, then the start of the east-going ebb. The previous night's full moon was an obvious reminder that we were right on spring tides, and that such slack as there was would be fleeting.
We reached a point where we could see into the narrow strait and it was immediately obvious that the last of the flood was pushing through from the east and encountering a larger body of water on the seaward side. A standing wave was breaking almost from shore to shore on an otherwise flat calm stretch of water marked only by the swirls of tidal offshoots.
Neither Maurice or Sam had been here before, and when Maurice saw the rolling wave, his only comment was "Tell me we're not going through that?!". His apprehension was well-founded, the Corryvreckan is a very active piece of water, and also features one of the world's most violent tidal whirlpools.
We reassured Maurice that the wave would drop away as slack water occurred, and sure enough it slowly split into two sections and dissipated, peeling back to the shore on each side of the strait. I think Sam was actually a little disappointed that we weren't hammering through at peak flow with huge seas......maybe some other time!
The narrowest part of the channel is less than 2km long, but takes a huge volume of water through on each tide. We reckoned that the actual slack water was less than five minutes before we began to feel the insistent pull of the ebb drawing us into the narrows. A few swirls and hydraulic cushions began to appear as the ebb started to establish but in the absence of swell things were very gentle.
Our timing had been good - we drifted through with little drama under a clearing blue sky. Just before we entered the channel Douglas had stopped at a small bay on the Jura shore where he met some Dutch sea kayakers who'd passed through in the opposite direction at the last part of the flood tide. Remarkably, they didn't seem to realise where they'd been paddling.....or the state of the tide.
Emerging from the narrowest part of the Gulf, we felt a small breeze at our backs and hoisted our sails. Just ten or so minutes after slack water, and we were being propelled into the Sound of Jura at 8kph without paddling.....it was what we hoped would be the start of a fast ride down to our finishing point at Carsaig Bay.

Corryvreckan - "a depe horlepoole quhairin if schippis do enter thair is no refuge but death onlie".....
At 1525 we launched from Port nam Furm to make our transit of the Gulf of Corryvreckan, intending to take advantage of the slack water period as the flood tide subsided.
This narrow channel running between the islands of Scarba to the north and Jura to the south has a fearsome reputation - the quote in the title of this post is from a 16th century "rutter" or pilot book compiled by Alexander Lyndsay, the pilot on James Vth's voyage around his kingdom. In the days of sailing ships the Admiralty Pilot warned against attempting the passage and even today in the age of powerful vessels and GPS, the current Admiralty West Coast of Scotland Pilot states that it is "very violent and dangerous" and that "no vessel should attempt the passage without local knowledge".
The Corryvreckan (speckled cauldron), third largest tidal whirlpool in the world, is only part of the problem. Huge volumes of water pass through the channel on both flood and ebb tides, on the north-going flood the water pours up the Sound of Jura and is forced through narrow passages to the north and west, the Corryvreckan taking a significant part of the stream. On the south-going ebb the process is reversed and water is forced through the channel from west to east.
The seabed in the channel approaches and the channel itself is very complex and accelerates the flow of water, producing tidal streams of up to 8 knots (16 kph). A complicating factor is a pinnacle on the north side of the channel which rises from a 219m deep "hole" to within 29m of the surface, with a very steep face on its eastern side. On the flood tide particularly, this topography combined with the speed of the flow causes a massive upthrust of water which surges past the pinnacle and sets up an enormous whirlpool with vortices spinning off downstream to the west. If you then combine this dynamic water with a wind and swell from the western entrance to the channel, the resulting conditions can be truly elemental with standing waves of up to 9 metres and a roar which can be heard up to 20 kilometres away.
As we set out, we met the tour boat "Sea Leopard II" coming eastward from the channel. As soon as he saw us, the captain throttled right back to minimise his wash - a courtesy we were grateful for; a wash in confused water can produce quite difficult waves. The video embedded on Craignish Cruises website is an excellent explanation and film of the Corryvreckan - and if you don't fancy kayaking the strait then the Sea Leopard II would be by far the best way to experience the whirlpool and the wildlife of the area. To get an idea of the power of the tidal stream at Spring tides, this video shows the RNLI lifeboat in the main flow.....
We were very cautious because from Port nam Furm it isn't possible to see what conditions are like in the Gulf itself. We expected some swell from the west due to strong winds in the preceding days, so it would have been unseamanlike and foolish to have attempted the passage when the flood tide (3 days before Springs) was running strongly.
As we entered the channel and gained a clear view to seaward we were relieved to see quiet conditions and no breaking swell - it appeared that our prospects would be somewhat brighter than "death onlie" ! As if stage-managed, the sunny conditions were replaced with a grey cloud sheet as we entered...
In the narrowest part of the channel the water was swirling and forming gentle hydraulic cushions, but our timing had been good and we passed through easily on slack water. One factor in our planning of time and tide for this passage was that if we encountered nasty conditions at the west side of the Corryvreckan we could wait a short time for the ebb to build and push us back through the channel to safer water in the Sound of Jura.
However, the timing needed to be calculated accurately - slack water lasts just minutes and the flow picks up very quickly. By the time we reached the west entrance the east-going flow could already be felt and paddling became a bit more strenuous.
On the Jura side of the western entrance are a couple of small islands and skerries. We passed inside Eilean Beag (little island) as the ebb began to really get started and had to PLF for a good 15 minutes to escape being drawn back through the Corryvreckan. For a good five minutes we were paddling at maximum output but making good just over 1kph against the strengthening tide. To see how strongly this section can run at full flow, the same bit of water is featured from the 9 minute mark in the HebrideanWild video.
After a strenuous pull we won safely clear of the Corryvreckan.......the wild west coast of Jura was now ours to explore.
