Trig point overlooking grassy farmland and the Firth of Clyde
Beginning at Largs Marina this final stage of the Ayrshire Coastal Path takes you right though the heart of the popular seaside town, before heading inland and uphill across boggy ground towards Knock Hill - an Iron Age Fort. From the trig point on a clear day your efforts will be rewarded with beautiful views across the Firth of Clyde towards the Clyde Islands of Cumbrae, Bute and Arran, as well as the Argyll hills and Cowal Peninsula. From here you head for Skelmorlie - the official end point of the Ayrshire Coastal Path, and along the way you'll pass a Secret Bunker, the pretty hamlet known as Meigle, and the impressive Skelmorlie Castle.

NOTE JAN 2025: Due to storm damage caused by Storm Eowyn there is a short 200m stretch of this route between Knock Hill and Routenburn Rd which is currently closed as fallen trees are completely blocking the path. I have described a diversion below which adds approx 1km. The closed section is the wooded Glen at the Blackhouse Burn (between the bottom of the field and the Routenburn Road). To de-tour around it, turn left at the kissing gate at the bottom of the field and walk along the edge of the bushes in a SE direction for approx 150m, where you can turn right (SW) to pick up a track. At some gates, turn right (W) to continue along the farm track, passing through a metal gate and then down onto the Routenburn Road. Turn right on Routenburn Rd to continue along the Ayrshire Coastal Path route.

DIFFICULTY RATING: Moderate. This is a hilly walk! Starting at sea level you gradually work your way up to Knock Hill summit via paved surfaces, farm tracks and hillside trails – nothing steep. The remainder of the walk is also hilly with plenty of sustained inclines and declines on single track roads, some of them steep. The hill trails are usually pretty wet and boggy (think of a giant peaty sponge). There are often sheep on and around Knock Hill. Three kissing gates and two large metal deer fence gates.

LOW ROAD OPTION: From Largs the Ayrshire Coastal Path splits into two: the high road (via Knock Hill as described here) or the low road via Routenburn Road. I would still rate the low road as moderate due to the amount of ascent and descent – don’t be fooled – you still go up quite high. The big difference is you stay on well-surfaced quiet roads, skipping out the (often wet and boggy) ascent of Knock Hill. Note however that the two routes merge and even the low road requires a lot of ascent and descent prior to reaching Skelmorlie.

  Car parks at Largs Marina (KA30 8EZ) and Wemyss Bay Train Station (PA18 6AR) where there is a charge. There’s a regular local bus service between Wemyss Bay and Largs with a handy bus stop across the road from Wemyss Bay train station. The provider is McGill’s – be aware that on my last trip the 11 minute journey cost a whopping £6.30 single! On the plus side, you can often see seals basking on the rocks as you journey along the A78 – not sure if that makes the price seem any better?!

TOILETS: There are public toilets on Largs Promenade (chargeable – contactless payment only) and at Wemyss Bay Train Station (free). Skelmorlie Secret Bunker is located approx two thirds of the way along the walk and welcomes Ayrshire Coastal Path walkers to use their portaloo during their opening times, which at time of writing are 1pm-5pm on weekends between April and September. Check their website for updates.

WALK REVIEW: 23RD APRIL 2017

There are two options for this final section of the Ayrshire Coastal Path: the low road and the high road. Despite the fact it is several miles longer and I had already walked 13 miles by the time I arrived in Largs, naturally I chose the high road! From what I had read it sounded more interesting and over the course of my 4 days on the Ayrshire Coastal Path I had experienced some amazing scenery along the higher paths. Plus I had never been up Knock Hill before 😉

My mum came along too, she wanted to do the last leg of my charity walk with me so had joined me in Portencross earlier in the afternoon. I don’t know why, but it wasn’t until I reached the final way marker that it really hit home I had just walked 100 miles! It wasn’t something I had given any thought to before embarking on the walk for the Mark McCloskey Foundation, but to have rocked up at Wemyss Bay with only myself to celebrate with would have been a real shame so I am truly grateful to my mum for walking all that way with me.  She was there for parts of the final two days and it gave me a great morale boost. As it was, my dad and family friend Archie came to collect us in Wemyss Bay and even walked the last mile with us. It was then off to Ardrossan for a well earned chippie!!

I have mixed feelings about this Largs to Wemyss Bay walk. I want to say it’s a great walk and I think it is, but I’m finding it hard to muster up the enthusiasm it deserves. I am confident that is only because I was so exhausted by the point of starting it that I couldn’t properly appreciate it. Largs just seemed enormous, a never ending promenade….(although it is worth mentioning that there are more benches in Largs than on the entire rest of the Ayrshire Coastal Path put together!!) and when we reached the A78 towards the end of the walk we both could have quit there and then when we realised that the uphill bits weren’t over yet! Now that I have been to the top of Knock Hill, I would consider trying the low road next time for a gentler, less boggy experience.

On a more positive note, the views along this walk were stunning and apart from the long walk through Largs, I found that things stayed interesting thanks to constant changes in terrain. I liked that it involved a bit of hillwalking too and I am wondering whether Knock Hill might be an option with the kids one day if I can find somewhere closeby to leave the car….

On your way along Brisbane Glen Road, keep an eye out for the Thomas Mackdougall Brisbane Cairn. The plaque on it reads “This cairn commemorates Sir Thomas Mackdougall Brisbane who was born in this glen in 1773 and died in Largs in 1860. He was Governor General of New South Wales from 1821-1826 and gave his name to the River Brisbane. This cairn was donated by the people of Brisbane, Australia and was erected in 1989“. The next part of the walk takes you right past the site of his former home, although there are no remains to be seen of it now. Brisbane was also a keen astronomer who published a catalogue of stars in the southern hemisphere and was awarded a gold medal from the Royal Astronomical Society. He founded Observatories in both Australia and Scotland – and the remains of one of these can still be seen today in Brisbane Glen close to the walled garden!

From the summit of Knock Hill the views were spectacular, definitely worth the short de-tour from the main track. This is the site of an Iron Age Fort.

Looking back towards Knock Hill – seemed so far away now!
A green shipping container-style building with a solar panel on the roof and signage relating to Royal Observer Corps and Museum. A group of walkers are standing beside it and there are views down over the Firth of Clyde.
Skelmorlie Secret Bunker and museum is a fascinating place! Completely restored back to its original condition in 2004, this underground nuclear monitoring post was operated between 1965 and 1991 by volunteers from 25 Group (Ayr) Royal Observer Corps Association. Members of that same group now conduct guided tours on Sunday afternoons between April to Sept. Tours last approx 90 minutes. Booking essential – see their website for details. The bunker sits right on the Ayrshire Coastal Path route and during its opening times, the volunteers offer walkers a warm welcome, use of their toilet facility as well as free bottle/flask refills (donation optional but much appreciated).
View from a single track road lined with hedgerows, heading downhill towards a large wooded area with part of a castle visible amongst the trees.
Pleasant minor road with Skelmorlie Castle visible amongst the trees and the Argyll hills standing behind. A downhill section for once!

Perfect end to my Ayrshire Coastal Path journey! It was like the universe was sending me a message of approval and congratulations 🙂
