If you’re arriving by train, bus, or taxi from the airport, keep tonight simple: get to Casco Viejo first and let the city introduce itself on foot. The old quarter is easiest to enjoy once the afternoon crowds thin out, and in June the light hangs around late, so you still have a proper evening to wander. The narrow streets around Siete Calles are mostly pedestrian, so leave the car out of it if you can; if you do drive, park once and forget it for the night, ideally in a garage near El Arenal or Abando. From here, it’s all about settling in and taking the first easy stroll.
Start with Casco Viejo, moving at a relaxed pace through the medieval lanes and little plazas that give Bilbao its old soul. This is the city at street level: shutters, pintxos bars, local shops, and the steady hum around Mercado de la Ribera if you pass by before it closes for the night. A quick stop at Santiago Cathedral is worth it even on an arrival evening; the Gothic interior is usually open into the evening, though hours can vary by season, and entry is generally free or donation-based for a short visit. Then drift into Plaza Nueva, where the arcades make it an ideal place for an aperitif. If you want a classic first pintxo, this is the moment to order a txakoli or a small beer and just watch the city move around you.
For an easy first-night dinner, head to Bistró Guggenheim Bilbao in Abandoibarra; it’s a practical choice after travel because you stay close to the riverfront and avoid overplanning. Expect roughly €25–40 per person depending on how many plates and drinks you order. From Plaza Nueva, it’s a pleasant walk of about 20 minutes through Arenal and along the river, or a short taxi if you’re tired. After dinner, finish with the most iconic view of the night: the exterior of Guggenheim Museum Bilbao. At dusk and after dark, the titanium curves catch the city lights beautifully, and the surrounding promenade is one of the best places to feel Bilbao’s modern side without committing to a full museum visit on day one.
From Bilbao, take Metro Bilbao Line 1 early enough to be at Puente Colgante right when the day feels fresh; this is the kind of outing that works best before the coast gets busy. The bridge is usually open from morning into evening, and the panoramic elevator/ferry crossing is only a few euros, so it’s an easy first stop. Spend about an hour here: walk the riverfront, take in the iron-and-cable structure up close, and if you like, cross over for the best estuary views before looping back. From there, it’s an easy onward move into Getxo proper.
Continue along Paseo de la Galea, where the pace changes completely: clifftop paths, sea air, and those big Basque villas set back behind gardens and hedges. It’s a lovely 1.5-hour stretch if you don’t rush it, with plenty of spots to pause for photos or just watch the water. A little farther on, stop at Muelle de Arriluze for a slower harbor-side breather — this is a good place to just stand and watch the boats before lunch. For eating, head into Puerto Viejo de Algorta and pick a casual restaurante or pintxos bar tucked into the old fishing lanes; expect roughly €20–35 per person for seafood, grilled fish, or a plate of pintxos with a drink. If you want a reliable, no-fuss option, this is the part of town where lunch is more about the atmosphere than the reservation.
After lunch, wander Puerto Viejo de Algorta itself for about an hour. The lanes are compact, a little scruffy in the best way, and full of local life — small cafés, old houses, and corners that still feel like a village rather than a suburb. Then finish with an easy seaside stretch at Playa de Ereaga. It’s a good late-afternoon reset: sit on the sand if the weather is warm, or just walk the promenade and watch the light change over the bay. If you’re staying into the evening, this is the nicest low-effort way to end the day; otherwise, it’s a straightforward ride back on Metro Bilbao from the Algorta area, with trains running frequently enough that you don’t need to plan it too tightly.
From Getxo, aim to be on an early Bizkaibus so you roll into Gernika-Lumo with enough time to settle in, grab a coffee, and start the day unhurried. Once you’re in town, begin at Museo de la Paz de Gernika: it’s compact, thoughtful, and worth the full visit for the context it gives to everything else you’ll see today. Plan on about 1 hour 15 minutes, with tickets usually in the low single digits; it’s the kind of museum that rewards slowing down, especially on a quiet weekday morning. A short walk afterward brings you to Casa de Juntas de Gernika, where the tree of Gernika and the assembly house make the political symbolism of the town feel very immediate. Give yourself about an hour here, and if the weather is decent, linger a little outside—the whole square has a calm, civic feel that’s easy to miss if you rush.
If it’s market day, let Gernika Market shape your lunch rhythm. This is the place for local cheese, peppers, bread, fruit, and a bit of people-watching before the town settles into siesta mode. Stay around 45 minutes and keep your lunch flexible: nearby around Plaza del Mercado, sit down at a traditional spot such as Boliña El Viejo or another no-frills comedor serving good Basque staples for roughly €18–30 per person. Think grilled fish, croquettes, or a proper menu del día rather than anything fancy. The best version of this part of the day is relaxed—eat well, then give yourself a few extra minutes to stroll the center before heading out of town.
After lunch, shift from town to landscape and head into Urdaibai Biosphere Reserve, where the pace changes completely. This is one of the nicest transitions in Biscay: marshes, estuary views, birds, and broad green edges that make the whole coast feel open and breathable. Depending on how you’re moving around, it’s easiest to use a car or a local bus connection and keep expectations simple—this is not a “tick every stop” afternoon, but a scenic, restorative one. Spend about 2 hours wandering viewpoints and riverside stretches, then finish at Laida Beach in Ibarrangelu, where the sand, estuary light, and Atlantic air make a satisfying low-effort ending. If the tide and weather are in your favor, it’s a lovely place to sit for a while before heading back; keep your return flexible, and if you’re continuing onward by bus, check the last departures earlier in the afternoon so you’re not watching the clock at the shoreline.
From Gernika-Lumo, aim for a mid-morning bus so you land in San Sebastián with enough daylight and no rush. Once you’re in the city, head straight into Parte Vieja, the old quarter’s compact maze of streets where the pace changes immediately: scooters, church bells, little bars opening shutters, and locals weaving through on coffee runs. Give yourself time to just wander a bit before locking into sights — this is one of those neighborhoods that makes more sense when you let it come to you. From there, step into Basilica de Santa María del Coro, just a short walk away, for a quick interior stop; it’s usually open in the morning, and a brief visit is enough to appreciate the ornate Baroque details and the contrast between the church’s calm and the busy streets outside.
Continue to San Telmo Museoa, which sits right on the edge of the old quarter and is one of the easiest cultural visits in town because it’s compact without feeling rushed. Plan around 1.5 hours here; tickets are typically around €7–€10, and it’s a good call to go before lunch, when your energy is still high and the galleries feel like a proper pause rather than a detour. Afterward, drift into Plaza de la Constitución, the old square with numbered balconies and a very local feel even when it’s full of visitors. It works perfectly as a breather before lunch — there are cafés all around, and if you sit for a few minutes you’ll get the rhythm of the neighborhood rather than just the sights.
For lunch, stay in Parte Vieja and do a slow pintxos stop on one of the classic bar streets — this is the moment to keep it informal and let the city do the work. A good strategy is to pick two or three bars rather than trying to force one “best” place; order a small plate or two at each, plus a txakoli or beer, and expect roughly €20–€35 per person depending on how much you drink. If you want an easy rule, go where the counter looks lively but not impossible to reach, then move on after one round. Don’t overplan it — the fun here is in the wandering, the standing at the bar, and the quick transitions between spots.
After lunch, make your way out to La Concha Promenade in Centro for the gentlest possible finish to the day. It’s an easy walk from the old town, and once you hit the bay the whole tempo softens: families on the sand, runners on the railings, and that long curved sweep of water that makes San Sebastián feel instantly recognizable. Give yourself about 1.5 hours for an unhurried stroll, and if you want a final break, grab a coffee or a drink near the promenade and just sit with the view before heading back.
Arrive in Getaria with enough time to settle in, drop any bags if you’re staying nearby, and head straight to Cristóbal Balenciaga Museoa before the midday flow picks up. It’s one of those museums that feels very “right” for the town: elegant, compact, and quietly ambitious, with tickets usually around €10–€12 and a visit that takes about 1.5 hours. If you’re an early riser, you’ll get the best light on the building and the calmest galleries; it’s usually open from late morning through early evening, but it’s smart to check the day’s hours in advance in summer.
From there, drift into Calle Mayor / Old Town of Getaria, where the town’s scale does half the work for you. This is a short wander rather than a destination march: stone lanes, small balconies, and those narrow coastal angles where the sea keeps appearing between buildings. Give yourself 45 minutes and no agenda. The nicest way to do it is simply to follow the slope downhill, stop for a coffee if the mood strikes, and let the old center show you how local life runs here when it’s not trying to impress anyone.
For lunch, make it a proper seafood stop at a restaurante on the harbor and lean into what Getaria does best: grilled fish, anchovies, and a long, unhurried table by the water. A sensible budget is €25–45 per person, depending on whether you go simple or add wine and dessert; in summer, reserving ahead is wise, especially if you want a terrace seat. After lunch, walk a few minutes up to San Salvador Church, a quick but worthwhile pause for the view and for the sense of the town’s layered history. It’s not a long visit—30 minutes is plenty—but the angle over the rooftops and harbor is one of the nicest in town.
Then ease back down toward Getaria Harbour and spend some time by the boats, breakwaters, and waterfront edges where the town feels most itself. This is the part of the day where you can slow right down: sit, walk, watch the tide, or just take a digestif stroll with no pressure. From the harbor, continue out to a Txakoli tasting at a local bodega near Getaria in the hills around town, where the tastings are often around €10–€20 and a visit runs about 1.5 hours. It’s the best way to end the route: coastal air, a glass of crisp white wine, and the countryside just beyond the village before you head on.
