The Hungarian Foreign Ministry's advices to would-be travellers to Benin:
If you want to travel to Benin you should pay attention to the danger of being infected by different tropical illnesses, the flaws of the touristic infastructure, the common power-cuts and the deficiency of fuel. We only recommend the travel with a person who knows local conditions very well. Hungarian citizens can only travel to Benin with a visa and with the required immunizations. We recommend to make contact with the consulate before your journey in order to obtain more information.
