City buses can be a challenge. They are more frequent during office hours, specially close to the University hours, so it's very likely that they will be crowded with students. Any other time, you'll probably wait very long for your bus, as sometimes they can take longer than an hour to come. Transporte Coletivo Grande Londrina (TCGL)'s website (http://www.tcgrandelondrina.com.br/) has bus lines and time tables, though it's not easy to find your way around it, either.
Taxis are frequent and to be found everywhere. However, Londrina's traffic sometimes won't help you, and you'll find red light after red light. Be prepared to pay R$ 15 to R$ 20 for short distances.

Lake Igapo Park. There are actually several lakes called "Lake Igapo". They are called, naturally, Igapó 1, 2, 3, and 4. There are several parks along the several lakes, but Lake Igapó 1 has the most well known. This park runs alongside the northeastern side of the lake, between Rua Herodoto and Avenida Amithas de Barros. Crossing to the north side of Avenida Amithas de Barros you come to what is called the "zerão" (big zero), which is another park that has a number of sports facilities.edit
Historical Museum of Londrina, . The museum is a project of the State University of Londrina (Universidade Estadual de Londrina - UEL) and is located in the old train station - which no longer has any track going to it.
