Barcelona travel tips
Stay connected in Barcelona by using free WiFi
Barcelona WiFi, developed by local authorities, is among the largest networks of free internet in Europe. With around 2,000 hotspots available, you can get online almost everywhere: in public transport, parks, even at the beach! Hotels, bars and restaurants often offer their own networks. Use online maps or message your near and dear without the fear of draconian roaming charges!
The Church of the Sacred Heart of Jesus is one of the best vantage points in Barcelona
Templo del Sagrado Corazon de Jesus sits on the top of the Tibidabo hill, one of the highest in the area. The church is remarkable for its architecture: the lower part, built in 1911, looks quite different in style and colour from the upper part, finished in 1961. The lower terrace has some breathtaking views to offer — the mountain rises more than 520 metres above Barcelona. However, you can also take the elevator to the upper observation deck (538 metres).
In Barcelona, swimwear is for the beaches, not for the streets
Location near the sea doesn’t make Barcelona a beach town. Don’t walk the streets half-naked in your beachwear. It might be acceptable in some areas of the seaside neighbourhood Barceloneta. However, it doesn’t apply to the whole city. Be especially attentive to your looks while visiting a religious building. Respect local worshipers and cover your shoulders and legs when you enter. A lightweight scarf may come in handy.
