Munitibar-Arbatzegi Gerrikaitz (Arbácegui y Guerricaiz)

The road signs can’t decide. One bend calls it Munitibar, the next Gerrikaitz, then Arbatzegi flashes past on a stone marker. All three names belong to the same scatter of farmsteads that slipped together in 1883 to make one of the smallest municipalities in Bizkaia—barely 500 souls stretched across folds of green that never quite flatten into a village green. Sat-navs give up, which is the first hint that you’ve left the coast’s weekend traffic behind.

High pastures, low horizons

From Bilbao the N-637 peels inland at Gernika, then the BI-638 starts to climb. Forty-five kilometres sounds like a doddle until the tarmac narrows, hedges turn to dry-stone walls, and every crest hides another 15% ramp. Allow an hour; the locals do. At 230 m above sea level the air is cooler and carries the smell of cut grass rather than tideline diesel. Oak and beech survive in the damp folds between pasture, giving way suddenly to open ridges where red-tiled caseríos stand alone, each with its own name painted on the gable. There is no centre to head for—just a choice of lanes that eventually loop back to the same small road.

The landscape is worked, not curated. Cows graze right up to the tarmac; hay bales sit under tin roofs older than the farmers. On a weekday morning you’ll meet more tractors than cars, and the drivers lift one finger off the wheel in greeting, the Basque version of a nod. Walkers following the Camino del Norte sometimes appear, boots caked in red clay, looking slightly surprised to find anywhere still serving coffee.

What you won’t find—and what you will

There is no medieval quarter, no gift shop, no ticket booth. The ermita of San Miguel de Gerrikaitz sits on a small rise above a farm gate; the key hangs on a nail inside the porch. Inside, whitewashed walls and a single baroque altar are lit by a 1970s strip light. The reward is outside: a 180-degree sweep of pasture rolling down to the Río Lea, with the coast hidden by low cloud that may or may not burn off by lunchtime. It is the sort of view that makes you check your watch, then sit on the wall anyway.

Civil-War historians know the name. On 23 April 1937—five days before Guernica—Franco’s planes bombed the main road here to stop Republican traffic. George Steer filed a despatch from the wreckage; the craters are long grassed over, but the event is remembered on a modest stone plaque fixed to a barn. No audioguides, no school parties—just the inscription and the wind.

Moving at grazing speed

The best map is the one you draw yourself. A lattice of farm tracks links the three original hamlets. One hour clockwise from the ermita takes you past stone threshing circles, a chestnut press converted into a toolshed, and a field where a single white pony watches every passer-by. Signposts exist, then abandon you halfway up a hill. Mobile signal evaporates on the northern flank of Mount Oiz; download an offline track if you insist on knowing exactly where you are, though half the pleasure is realising the valley behind has disappeared in mist and you can still hear a chainsaw somewhere below.

Cyclists need low gears—gradients hit 18% without warning, and descents are short enough to keep fingers frozen on the brakes. Drivers should pull in at the first lay-by that appears; the next one may be in the next province. Everyone shares the same surface, which keeps speeds honest and tempers calm.

Lunch when the bar is open

The Sindikatu bar is easy to miss: a green shuttered house beside the junction, open roughly 12:00-15:30 if someone feels like it. Inside, three tables, a television permanently on mute, and a handwritten list that rarely changes—tortilla thick as a doorstep, croquetas the size of golf balls, a plate of jamón you’ll finish even if you meant to be vegetarian. A glass of cider costs €1.80; the barman will demonstrate the long pour if you ask, but won’t laugh when half lands on your shoes. They’ll stamp a pilgrim credential for free, though you may have to ring the bell on the counter twice.

There is no shop, cashpoint, or petrol pump. Stock up in Gernika before the final climb; the last ATM is 15 minutes away in Markina-Xemein and it charges €2 per withdrawal. If the Sindikatu is closed, the nearest proper meal is a caserío south-east toward Aulestia where chuleton de buey arrives sizzling on a ceramic tile, sliced for two and served with proper chips. Vegetarians get pisto—a smoky ratatouille topped with a fried egg that can be left off if you negotiate in advance.

Seasons and moods

Spring brings meadows loud with frogs; by May the first hay cut lies in long strips across the slopes. Summer is warm but rarely hot—midday in the sun can hit 28°C, yet five minutes into the woods you’ll wish for a jumper. Autumn colour starts in late October and lingers through November, when morning mist stays until coffee time. Winter is quietest: daylight shrinks to 9-16:00, roads ice over in shadow, and the handful of guesthouses drop their prices by half. Access is still possible, but carry chains and don’t trust the weather app—cloud can clamp down for days.

Beds, barns and honesty boxes

Accommodation is scattered, not stacked. Garro farmhouse rents two attic rooms with under-floor heating and views across its own apple orchard; breakfast includes eggs you watched being collected. A little further on, a converted stone mill offers self-catering for four—wood stove, no television, honesty-box honesty. Book ahead; hosts often work the fields and aren’t there to open gates on spec. Prices hover around €80 for a double, less mid-week, and every host knows the next one along the valley—miss your turning and they’ll phone ahead to hold the door.

The coast is only 20 km away as the crow flies, yet the psychological distance is greater. You could breakfast here, be on the beach at Lekeitio by 10:30, and still return for dinner—but most people don’t. The village works its slow spell: boots stay by the door, the horizon feels far enough, and the evening plan stretches no further than watching the sky fade from the ermita wall while a tractor threads its way home through the fields, headlights picking out stones older than any map.
