After two days in San Jose, I went south again to gather myself and see what is next. I applied for different kinds of volunteering options in Costa Rica and in Nicaragua. Costa Rica is just too expensive to travel around with a tight budget. The night before I took a decision, the options were either to go to Nicaragua or hope that a volunteering option replies in Costa Rica. Both option answered. I will now stay some time here in Costa Rica volunteering in the jungle :)
