Avinguda Tibidabo is a station of the Barcelona Metro and is the terminus of FGC-operated line L7. The station is situated under Carrer de Balmes at Plaça de John F. Kennedy, the former street's junction with the Avinguda Tibidabo and Passeig de Sant Gervasi.
The station was opened in 1954, along with the rest of the branch from the junction at Gràcia station. It has a single terminal track, which ends at a buffer within the station. Just outside the Gràcia end of the station, this track diverges into the twin running tracks of the L7. The terminal track is flanked on both sides by 66 metres long platforms, which can accommodate a three car train.
