Registration itself is an easy process: log on to the official website www.rio2013.com and fill in the form with your personal data. Individuals can either choose to join an existing group or book singularly.
Accommodation and meals are provided and included in different packages, with prices ranging from around 50 to 300$, depending on the length of your stay and your country of origin. All packages are payable directly online by credit card or bank transfer.
If you or your group need a visa for Brazil, plan well ahead: the process might take a few days! Free visas are available: visit the Brazil Ministry of Foreign Affairs website, complete an online form and take it to the Brazilian embassy in your country, together with your passport and proof of registration to World Youth Day.
When you're done and ready to go, why not check out the special so called 'pack peregrino', available on the online shop. It contains everything the pilgrim needs, from caps and waterproofs to backpacks and the essential water bottles.
