Every year, tourism grows in Curitiba. To attend this demand, the "Linha Turismo" ("Tourism Line") started in 1994. It is a special city tour that visits the principal tourist attractions in Curitiba, featuring comfortable white buses with big windows and a shape similar to that of streetcars. The vehicles have a sound system that plays recorded messages describing sites in three different languages: Portuguese, English and Spanish. It is possible to visit the parks, squares and the rest of the city's tourist attractions. Considered one of the best in the country, the "Linha Turismo" is available every thirty minutes and has a two and a half-hour tour, which travels around forty-four kilometers. To go on the tour you must buy a ticket with five tickets that give you the right to get on and off bus four times. Users can therefore choose the touristic point where they want to stay longer. Then, they can embark again to complete the remaining part of the itinerary. Today the line goes to 25 key reference points in Curitiba, completing 44 km in 2 and ½ hours.
