March: Sant Medir and the congress city
March brings the calendar's sweetest festival — Sant Medir and its candy rain — and the week when the world of mobiles lands in town with the industry's global congress.
Sant Medir, early March
The Sant Medir parade fills Gràcia and the old town with floats throwing tons of candy: the sugary-est festival of the year, over a century old, with lifelong troupes.
Mobile World Congress
In late February or March depending on the year, the world mobile congress transforms the city: full hotels, high prices and an international air. If you're not here for it, pick another week.
Spring in the parks
The Laribal gardens and the Collserola rose garden burst in March: the perfect time for green Barcelona before the heat.
