How busy is the Museu Blau?
It's out of the tourist centre, by the sea at the far end of Diagonal, and most of its visitors are local families and school classes. That gives it a very predictable rhythm: school groups on weekday mornings during term, families on weekends, and a rush when entry turns free at 3 pm on Sundays. The busiest spot inside is the entrance hall below the whale skeleton, where everyone stops for a photo.

Tickets and prices
Who pays the reduced rate
Ages 16-29, over 65s, unemployed people, families with up to two adults and at least one child under 16, large and single-parent family card holders, Barcelona library card holders and groups of 10 or more. That family rule is generous: two parents with children pay €2.70 each for the permanent exhibition.
Who gets in free
Under 16s, Barcelona Card holders, ICOM members, working tourist guides, teachers, journalists and a few other accredited groups. Bring proof.
Tickets are sold online through the city's museum ticketing site and at the desk. Booking isn't mandatory for a normal visit.
Skip-the-line: what actually works
There's no skip-the-line ticket, and the ticket desk queue is short on paying days. The real tactic is timing:
- Come on a weekday after lunch. School groups have usually gone.
- If you want it free, choose a normal Sunday at 3 pm over the first Sunday of the month. You get five hours, and it's less of a scramble than the all-day free Sunday.
- Check the ticket site before a free Sunday. Free entry may need a reservation, and getting it online saves time at the desk.
- See the temporary exhibition first on busy days; it's smaller and fills faster.
What to see
The whale
A 20-metre whale skeleton hangs over the entrance stairwell. The whale stranded on the Costa Brava in the 19th century and was named Brava after a public vote. Look at it from both the bottom and the top of the stairs.
Planet Life
The permanent exhibition, across about 3,000 m², tells the story of life on Earth through the museum's collections of minerals, fossils, animals and plants. It's laid out as a journey, and the open floor makes it easy to wander.
Science Nest
A hands-on space for young children. Ask at the desk whether it's open and at what times on your day.
Temporary exhibitions
Changing shows, such as the recent Invisible Animals. Worth the combined ticket if the theme appeals.
The building
The triangular, blue Forum building was built for the Universal Forum of Cultures and is one of the city's best-known modern buildings. Walk round it and to the Forum's seafront esplanade afterwards.
Tips by visitor type
Families
Probably the best-value family museum in Barcelona: under 16s free, adults on the reduced family rate. Go on a Saturday morning or a weekday afternoon in the school holidays, rather than a free Sunday.
Short on time
One hour covers the whale and the highlights of Planet Life. It's a long metro ride from the centre, though, so it suits a half-day combined with the beach at Diagonal Mar or the Forum.
Cyclists
There's free bike parking for 30 bikes by the entrance and a Bicing station on Avinguda Eduard Maristany.
Getting there
Plaça Leonardo da Vinci 4-5, Parc del Fòrum, at the end of Avinguda Diagonal by the sea.
- Metro: L4 (yellow) to El Maresme | Fòrum, Rambla Prim exit.
- Tram: T4 to El Maresme | Fòrum.
- Bus: H16, 7 (Diagonal Mar stop) and B20.
