Things to Do in Bilbao in April
April weather, activities, events & insider tips
April Weather in Bilbao
Is April Right for You?
Advantages
- April sits in the sweet spot between winter rains and summer tourism increase - you'll find tables at Asador Etxebarri without the month-ahead booking dance, and the Guggenheim's titanium scales catch that soft northern light photographers dream about
- Basque cider season is still flowing strong - sagardotegi cider houses in the hills above town keep their huge barrels open through April, serving unlimited cider with cod omelets and txuleta steaks in barn-like dining halls where locals sing traditional songs between courses
- The Ría de Bilbao's tidal rhythms create perfect walking weather - mornings start crisp enough for a café con leche on Plaza Nueva's colonnades, afternoons warm to that ideal 18°C (64°F) where you can explore Casco Viejo's Seven Streets without breaking a sweat
- Semana Santa (Holy Week) processions transform the old town into something medieval - hooded penitents carrying ancient statues through cobblestone streets, the smell of beeswax candles mixing with sea air, and spontaneous hymn-singing that echoes off 600-year-old stone walls
Considerations
- That famous Basque coastline turns moody in April - the Cantabrian Sea hasn't warmed past 14°C (57°F), so beach days at nearby Plentzia or Sopelana require serious determination and probably a wetsuit
- Rain arrives in theatrical bursts rather than gentle drizzles - one April morning you might wake to find the Nervión River running brown with mountain runoff, and those scenic bridges suddenly look less charming when you're sprinting between awnings
- Hotel rates start creeping upward mid-month as Spanish domestic travelers begin their spring getaways - what costs less in early April jumps noticeably during Easter week, and the city's compact size means there's nowhere to hide from the price increase
Best Activities in April
Pintxo Crawls in Casco Viejo
April's mild evenings were made for pintxo-hopping - the traditional Basque version of tapas that involves toothpicks, standing room only, and conversations shouted over counters. Start at 7 PM when bars along Calle Somera start laying out gilda skewers (anchovy, olive, pepper) and work your way to Plaza Nueva where locals debate football over txakoli wine poured from height to create natural bubbles. The weather means you can comfortably stand outside even when bars spill onto streets, and April crowds are still manageable enough that bartenders have time to explain what you're eating.
Guggenheim Architecture Tours
April light transforms Frank Gehry's titanium masterpiece into a living sculpture - the low spring sun hits those curved walls at angles that make photographers weep. Morning tours catch the building's eastern face glowing copper-gold, while late afternoon sessions show the titanium shifting from silver to rose as clouds move across the Atlantic sky. The museum's outdoor sculptures - Jeff Koons' Puppy flower sculpture and Louise Bourgeois' spider Maman - photograph best in April's soft light without the harsh shadows of summer.
Basque Coast Mountain Biking
The hills behind Bilbao turn emerald green in April - perfect singletrack conditions when winter mud has dried but summer dust hasn't arrived yet. Routes from Mount Artxanda (300 m / 984 ft above the city) drop through pine forests to medieval fishing villages like Algorta, where you can finish with grilled sardines at a harborside bar. The weather means you can ride all day without overheating, and coastal trails offer views of wild Cantabrian beaches that stay mostly empty until June.
Txakoli Wine Route Tours
April is when the txakoli grape vines along the Basque coast start showing their first leaves - perfect timing to visit family wineries where this slightly fizzy white wine has been made since the 1800s. The route from Bilbao to Getaria (24 km / 15 miles) passes through microclimates where Atlantic fog meets mountain sunshine, creating grapes with that signature mineral bite. Wineries offer tastings paired with anchovies caught in nearby ports, and you'll learn why locals pour txakoli from height to create its characteristic slight effervescence.
Nervión River Kayaking
Spring tides create ideal conditions for paddling Bilbao's urban river - the Nervión's ria system means you're technically kayaking through a drowned river valley rather than a traditional river. April's moderate rainfall keeps water levels perfect for navigating past the Guggenheim's titanium curves, under historic bridges like Puente de la Salve, and into the working port where you can watch fishermen mend nets. Morning sessions catch the city waking up - delivery boats bringing produce to riverside markets and locals jogging along Paseo de Abandoibarra.
Cider House Food Tours
April marks the tail end of cider season - sagardotegi cider houses in the hills above Bilbao keep their massive barrels open through month's end, serving unlimited cider with traditional menus of salt cod omelet, grilled txuleta steak, and Idiazabal cheese. The ritual involves catching cider in thin streams from height into wide glasses, creating natural carbonation. These aren't restaurants - they're working farm buildings where you eat at long wooden tables with locals who've been coming for generations, and the evening ends with spontaneous Basque singing that echoes off stone walls.
April Events & Festivals
Semana Santa Processions
Holy Week transforms Bilbao's Seven Streets into a medieval theatre - hooded penitents from centuries-old cofradías carry baroque statues through cobblestone alleys, creating a sensory overload of beeswax candles, incense, and centuries-old hymns echoing off stone walls. The processions peak on Good Friday when thousands gather at the 14th-century Santiago Cathedral to watch the 'Paso del Cristo' statue carried through streets where the only light comes from candle-holding faithful.
Bilbao International Documentary Film Festival
This under-the-radar festival turns the city into cinephile central - screening venues from the curved Guggenheim auditorium to tiny Casco Viejo bars show documentary films that rarely reach commercial cinemas. The programming leans heavily toward Basque and Spanish documentaries, with Q&A sessions where directors discuss their work over pintxos in neighborhood bars that become unofficial festival headquarters.
