The route
This is the classic way out of the Picos when you don't want to blast the motorway. Potes at the foot of the Fuente Dé cable-car, up the CA-184 over the Puerto de Piedrasluengas at 1,335 m, then a slow, winding descent along the CL-627 into Palencia, hop over to the CA-281 down the Nansa gorge, sweep west through the Cabuérniga valley on the CA-182, then N-634 and A-67 through Torrelavega to Santander harbour.
Pins are motorcycle-friendly stays other riders have vetted — in Potes at the start, along the two valleys in the middle, and around Santander for the ferry.

Track vs. route — how to load this into your GPS
What you're downloading is a GPX track — a dense, road-snapped breadcrumb of the exact line, with elevation on every point. It's not a GPX route (a short list of turn waypoints your device re-plans between). Tracks preserve our road choice; routes let the device pick its own way and can send you down a boring motorway shortcut.
How to use it on your navigator:
- BMW Navigator / Garmin Zumo / zūmo XT: import as a track, then Convert to Route (or Trip Planner → new trip from track) if you want turn-by-turn prompts. Keep Recalculation off so it stays on our line.
- TomTom Rider: import the GPX in MyDrive — it loads as a track / itinerary. Enable Follow the exact route so it doesn't re-plan.
- Calimoto: open the GPX and choose Import as tour — Calimoto follows the track line.
- Kurviger / komoot / MyRouteApp: open the GPX and pick Import as track to keep the road choice. Only choose Import as route if you want the app to re-plan for your bike profile.
- Google Maps / Apple Maps: these don't read GPX. Use the map on this page for turn cues, or import the file into a GPX-capable app first.
Rule of thumb: if your device asks "track or route?", pick track to ride our exact line — pick route only if you want the device to re-plan.
Elevation profile
From ~-3 m at the base to 1348 m at the top — 3,592 m of total climbing across the route.
The Piedrasluengas is a quiet, wide, well-surfaced pass with almost no traffic on weekdays. The real character is the descent afterwards: 40 km of narrow, tree-lined mountain road following the Nansa river north, then the wide-open pastoral sweep of Cabuérniga where the road opens up and you can settle into a rhythm.
By the time you drop into Cabezón de la Sal you're back in fast-transit territory — N-634 and A-67 into Santander take about 45 minutes. If you're catching the Brittany Ferries boat, aim to be in the city by mid-afternoon so you can park up, walk down to the Sardinero, and eat before boarding.
The road, honestly
Nobody rides this expecting hairpin drama. It's the antidote to a week of Alpine cols — a low, green, empty mountain crossing where the story is the landscape rather than the corners. The Piedrasluengas itself climbs gently, tops out below the tree line, and drops even more gently on the far side; a 1,000 GS will feel more at home here than an S1000RR.
The best bit is the middle: the CA-281 through the Nansa valley is a single-file road through beech forest with occasional villages, waterfalls off the roadside, and cattle wandering across the tarmac at dawn. Ride it slowly.
When to go, weather and fuel
April through October. The pass is technically open year-round but snowfall closes it in January–February most years; check inforcarreteras.es before committing. May and September are the sweet spot — full colour on the trees, temperatures in the high teens, no coach tours.
Fuel in Potes at the start and in Cabezón de la Sal near the end. There is nothing usable in the middle — top up before you leave Potes. Coverage is fine on 4G everywhere except the top 5 km of the pass itself.
Where to base yourself
Potes if you want two days in the Picos — take the Fuente Dé cable car in the morning, ride to Santander in the afternoon. Santander if you're on a ferry schedule — the ride works well as a same-day arrival into the port. Cabuérniga makes a lovely quiet middle-night stop if you have three days.
What to see along the way
- Fuente Dé cable car — 10-minute spur from Potes at the start. Not on the GPX but worth a morning if you're staying in Potes.
- Puerto de Piedrasluengas (1,335 m) — The high point. Wide viewpoint over the whole southern face of the Picos. Cold coffee stall at the top in summer.
- Nansa waterfalls (CA-281) — The road passes half a dozen roadside cascades between Puente Pumar and Puentenansa. No signposts, just look up.
- Bárcena Mayor — Short spur off the Cabuérniga road. Preserved medieval village — cobbles, stone houses, one restaurant, no cars.
- Santander old town — Waterfront harbour, the Palacio de la Magdalena on its own peninsula, and El Sardinero beach 10 minutes east.
