Walk 249 – Kilchattan Bay Circular, Isle of Bute (The West Island Way) – 5 miles

Widely declared as the most beautiful section of Bute's West Island Way, this charming circular walk at Kilchattan Bay is packed full of interest. From rugged (exciting?) terrain, to a remote lighthouse, hidden bays and lochs, panoramic views and historic places of worship, I think this walk truly has it all! It is fully way-marked and just a short ferry and bus ride from Wemyss Bay on the Ayrshire/Inverclyde coastline.

TERRAIN: Graded Moderate. A mix of paved surfaces, gravel, grass, narrow rocky hillside trails, and bracken (in summer) . One section where the path has eroded and a wire handrail has been placed to assist walkers. One set of steps near the end. Fairly flat for first half then undulating with a steep descent at the end. Lots of gates along the route and possibility of both sheep and cows.

  From the ferry terminal at Rothesay take bus number 490 to Kilchattan Bay. If driving there are a few parking spaces at the old pier, or on-street.

Walk Report: 22nd June 2025

I’d never been to the Isle of Bute, or so I thought. Mum tells me I was there when I was about 10, but I have no recollection of it. So I was super excited to be heading there with a fantastic group of walking friends to start the West Island Way.

We’ve all walked the Ayrshire Coastal Path together, finishing at Wemyss Bay where the ferry sails from. So it seemed fitting that we were all back there today off on another adventure.

Transport went like clockwork, with the ferry leaving on time and the bus waiting for us at the other side to deliver us to Kilchattan Bay. After what felt like quite the journey already, we had finally arrived at the start point of our walk. It was pouring, exactly as forecast! So after a small delay whilst people pulled on waterproofs, and then another small delay whilst people used the public loo, we were off!

Our group arrived in Kilchattan Bay by bus – here we are at the small pier where there is a public loo. With the picnic benches it would also be a lovely spot to sit at on a nicer day. Note the boats parked on the roadside to the right of the photo, which I found quite amusing!

I’d read a few things about this walk in advance: there was to be a rough bit near the start which would be the trickiest part of the whole Way; the walk we were doing today would be the most beautiful of the Way; that we could look forward to fantastic views; and a highlight would be the ruins of St Blane’s Church. I knew there was a lighthouse, that the walk was around 5 miles, and that it would start off flat before heading gradually up and up and up, before a final steep descent.

All of that turned out to be true. Apart from it being the most beautiful section of the West Island Way: I’ll reserve judgement on that until I’ve walked it all!

The ruins of St Blane’s Church – a definite highlight of the walk, and a truly peaceful spot. There’s an information board onsite which tells you more about it, so I won’t spoil the surprise.

The rough bit was a bit rougher than I’d anticipated. I certainly hadn’t expected to be putting my trust in a length of wire rope pegged into the ground. How exciting! I’m not sure my walking buddies shared in my excitement 😉 However it held the weight of all 17 of us (not at the same time I’ll add) and I certainly wouldn’t fancy trying to get along that short stretch without it. I’ve since read that this is a fairly new addition due to the path below eroding into the sea. And there is ample warning given in advance via some cautionary signage.

It was indeed rough in places, especially if compared to the rest of the day, and if you are not used to such terrain. These rocks were also very slippery when wet.
Hold onto the chord for dear life and you’ll be fine! This has been installed here because the original trail – lower down the slope – is badly eroded.

Speaking of signage, the team has done a brilliant job on the way-marking. We did encounter several sections of very high Bracken on our visit. Nothing that would stop us, it probably slowed us down a bit though as it was tricky to see what was underfoot. And at least one of our group came home with a tick, with the Bracken being blamed! I understand that the route is cared for by volunteers from the Bute Conservation Trust. They post regularly on the West Island Way Facebook page if you’re interested in staying up to date on work being done.

One of the highlights of this walk are the views. Spending so much time on the Ayrshire Coast as I do, it felt so strange being on the other side! It took me a while to get my bearings. I felt a strange mix of comfortably familiar, yet at the same time intriguingly unfamiliar.

Millport….. oh wait, no, that can’t be Millport because it would be tucked into that bay and out of sight, so where is that? Oh it’s the caravan park on the south-western tip of Cumbrae!

Largs and Knock Hill where some of us had been last month on the final section of the Ayrshire Coastal Path to Skelmorlie. It looked a long way to Skelmorlie from Knock Hill at this angle!

And then Arran came into view…. just WOW! That mountain ridge is something else seen from here! With Holy Isle to the far left, that meant Goatfell was also the peak furthest left: very unusual for me as I pretty much always see Goatfell on the right of the range from the mainland! I realised what I was looking at was the view I was familiar with from visits to Sannox, where I’d spent many a childhood summer holiday. But today I was seeing that same view from a distance away, a whole new perspective. It got me thinking…. all those days I spent on the rocks at Sannox Beach thinking I was looking onto the mainland, was I in fact looking over to here: the southern tip of Bute?! Probably some of the time, yes.

That first view of Arran – wow!

Just when we thought we’d seen it all, we reached the highest point on the walk, which incidentally is quite near the end! We were standing directly above where we’d been earlier in the day, and that height gave us a whole new outlook. Not only could we see that fantastic never-before-seen view of Little Cumbrae Island and (not) Millport, but from this higher ground we could also see over the top of all that, with Hunterston Power Station stealing the limelight! To most people it would be an ugly industrial sight, but to us it brought back memories of the day when we walked the Portencross to Largs section of the Ayrshire Coastal Path, which passes right in front of Hunterston.

And there were the views to places I couldn’t name – refreshing for someone who spends so much time walking in the same places all the time! One example is the sandy beach which comes into view on approach to Suidhe Chatain: I spent a while looking at the map trying to figure out if it would be Dunagoil Bay, or Lubas Bay, or Stravanan Bay… I’m still not sure. My best guess is Stravanan, which if true is quite exciting as we’ll be there on a future walk!

Another example is turning the corner after an uphill stint, to be welcomed by Loch na Leighe down beneath us. I knew to expect a loch – I’d been following a map – but I didn’t know it would be that pretty 🙂

Amongst the other memories which will stay with me from this walk are the 70th birthday celebrations held overlooking the lighthouse: the Happy Birthday song…. three boxes of Mr Kipling French Fancies displayed lovingly on a rock….. one candle which I couldn’t light….. the look on Morag’s face 🙂 Special moments to be treasured.

We’d decided to have lunch at that spot, and whilst a few of us walked out to the lighthouse for a closer look first, the rest had started eating. My mum was last to arrive for lunch and I’d joked to everyone that when she got there we should all get up as though were were ready to leave. They thought I was a meanie of course, but I said it wouldn’t worry her, she would simply reply (in a sarcastic tone) “Aye well, you go ahead!”. When she arrived I announced, “Right are we all ready to go?” and her reply, right on cue, and in the exact tone I’d jested, Aye well you go ahead! A roar of laughter lit up our wee corner of Bute 😀

Glencallum Bay – I’d originally planned to have lunch here, however as we turned the corner at the lighthouse a strong south-westerly hit us so we decided to use the relative shelter of the rocks there instead. Once down on the bay, it was surprisingly calm! There is some high ground inland from here which was probably offering some protection. Some of us remarked on what a lovely camping spot this would make.

I’ll leave you with this photo – because it’s my absolute favourite from our day on Bute. Taken towards the end of our walk on one of the highest points. Arran looking simply spectacular.
