Local Information


Curitiba is the capital and largest city in the Brazilian state of Paraná, located in the South of Brazil. It is well regarded for its solutions in sustainability and for its high level of human development. It is also an important gastronomic and cultural center.


Curitiba has many charming and interesting tourist attractions, such as the Wire Opera House, the Botanical Garden, and several parks. Good tour suggestions also include a visit to the Telecommunication Tower for a panoramic view of the city on a clear day; and the Oscar Niemeyer Museum, a cultural institution of international significance by its magnificence, beauty, and the importance of its collection. For more information, please refer to this city tour.

The harmony between the city and the environment has become a tourist attraction on its own. With the infrastructure in place to meet the needs not only of residents but from tourists alike, Curitiba is very well prepared to welcome visitors.

Only a few hours away, you can visit beautiful cities. In Ponta Grossa, located 100km (62 miles) from Curitiba, you find the Vila Velha State Park, the main natural attraction of the region, where you can take a closer look at large craters with exuberant vegetation and groundwater, beautiful rock formations with varying contours, as well as Lagoa Dourada (Golden Pond), which gets its name from its glinting golden waters from the reflection of the sunset. Another tourist spot in Ponta Grossa is the Buraco do Padre, a cave that occurs at the intersection of geological faults. You can access the interior of the cave, where there is a waterfall with remarkable sandstone displays.

A few kilometers from Curitiba, you also find the historic city of Morretes. You can get there by car or taking a train by the railway inside the ecological reserve of Serra do Mar, in all its charm. Both ways will guarantee beautiful scenery and fantastic photos.

Climate and temperature

Curitiba's altitude is almost 1km, and the city has a rainy spring with temperatures between 10 and 25 Celsius.

Local cuisine

The menu brings surprises to visitors for being so varied. The dishes of the local cuisine are a reflection of the history of the municipality and the typical foods, themselves, are very tasty. Curitiba's cuisine has mainly Italian and German inspiration.

The Barreado is very recommended. Very popular all over the State of Paraná, the Barreado consists of several cuts of beef slowly cooked over 12 hours on a clay pan. Manioc flour added with water is used to seal the pan, preventing steam from coming out. Once done the meat just falls apart. To be served, you add manioc flour and put the broth along with the meat on top of it.


We strongly suggest that all the participants book the hotel as soon as possible, warned that the payment does not need to be made right now. In the booking confirmation, the hotel will inform the payment due date.

The first two hotels described below (San Juan Executive and Victoria Villa) are side by side, less than 100 meters from the venue. Both have similar breakfasts, with breakfast at Victoria Villa being a bit more rich. San Juan will be the official hotel of the workshop, where the welcome cocktail (on Sunday) and the registration will take place.
