From the Torre de Sant Sebastian, a cable car line runs to Montjuic, the hill overlooking Barcelona. At 90 meters high, views of the city are stunning. The ride lasts about 10 minutes and deposits passengers in the park near the Estadi Olympic.
The last ride departs at 8p.m., a good time for watching the sunset from the top of the hill. The park is open at night to enjoy views of the city lights, and returning down the hill to the metro is a short walk.
