I left Enniscrone on a Tuesday morning in the second week of November, and the first thing I noticed was that I hadn't seen another cyclist since Donegal. Not one. The road south towards Ballina was mine, which sounds romantic until you're forty minutes in and realising the café you'd earmarked in Skreen had a handwritten sign on the door: Closed until Easter. Thank you for your support.
That's November on this route. You should know that going in.
The Sligo section sits roughly between Mullaghmore in the north and Killala Bay as you push down towards Mayo. It's not the most dramatic stretch on paper. No fjords, no mountain passes that stop you mid-climb to stare. What it has instead is a kind of lateral, wide-open quality. The light in late autumn does something strange here. It comes in low from the Atlantic, hits the damp road and turns everything the colour of old pewter. Some people find that bleak. I find it hard to leave.
But the practicalities are real, and I'd rather be honest about them than pretend November is just a quieter version of July.
A good chunk of the tourist-facing accommodation closes from late October. The hostels in particular. A couple of the smaller B&Bs I'd noted from a previous summer ride had gone fully dark, no answer at the number, no response online. If you're planning a multi-day loop through this section in November, you need to ring ahead and confirm before you commit to a route. Don't assume. I ended up in a fine guesthouse just outside Dromore West because the owner answered her phone on a Sunday evening and said yes, come on, there's no one else in. That's the off-season in a sentence, really. The people who are open are genuinely glad to see you.
Daylight is the other hard constraint. You're working with roughly eight hours of usable light, sometimes a bit less if the cloud comes in from the west. I was riding loaded, so I wasn't covering huge distances anyway, but I still had to be honest with myself about start times. Leaving after nine meant arriving somewhere in fading light, which is fine when you know the road and less fine when you're not sure where you're stopping. If you haven't thought about how your bike is set up for touring in variable conditions, autumn in Sligo will make that very clear, very quickly. Mudguards, lights, layers you can access without unpacking everything. These stop being optional.
What nobody mentions about November riding here is how good the roads feel. There's almost no traffic on the secondary routes. I went through a stretch near Easky without seeing a car for the better part of an hour. The surface on those roads is imperfect, as it always is along the coast, but there's something meditative about having them entirely to yourself. You start to notice things. A heron standing in a flooded field. The smell of turf smoke drifting from somewhere you can't see. Seaweed on the road from the last high tide.
Knocknarea is worth the detour if your legs are holding up. The climb is short enough, the view from the cairn reaches all the way to Donegal on a clear day, and in November you will almost certainly have it to yourself. I sat up there for twenty minutes eating a slightly crushed cheese roll and watching a squall build over Benbulben. I can think of worse ways to spend a Tuesday.
Sligo town itself is useful as a resupply point. The supermarkets and the bike shop are open, the coffee is good, and if you need a rest day it has enough to do without feeling like you're stuck. I stayed a night and sorted a minor issue with my rear derailleur before heading south.
If you're used to grinding into headwinds on the northern sections of the route, Sligo in November feels almost sheltered by comparison. The wind still comes, but the coastline bends enough that you catch occasional lulls. Not always. But enough.
Go in with flexible plans, a confirmed place to sleep each night, and food you're not relying on a café to provide. Do that, and November in Sligo is genuinely one of the better experiences this route offers.
