I am wondering about the rules for WWOOFing (working in an organic farm for a part of the day in exchange for a bed and sometimes a breakfast/multiple meals) or work exchange (same thing but for other types of tasks) in Costa Rica.
I have read some question here for long-term residents in Costa Rica wanting to work. This shows that one cannot steal the work of a Costa Rican, in short, which is a rule common to many countries.
However, I would like to visit Costa Rica as a tourist, I will travel for most of my trip but I saw one hostel offering work exchange, a couple hours per day of work in exchange for a bed (I would not get paid). I am thinking it could be a good idea to extend my trip for a couple more days but I do not want to go against the law. It would not be my main activity. Also I do not need a visa as a tourist (I am a French citizen).
I have tried to find information on the WWOOF Costa Rica website but beside saying they do not provide a visa, they do not say if I need a specific visa for work exchange.
So I am wondering, could I do some work exchange (no money received) in Costa Rica as a tourist?
