Every August, Massimino holds a small festival in honour of local hospitality — an event that takes on extra significance in a village this small, where the arrival of any visitors is an occasion. The format is essentially a communal meal outdoors, with local food, local wine, and conversation between the few dozen residents and whoever has found their way up the valley. It is the kind of village festival that is disappearing from much of rural Italy but that the smaller mountain communes still manage to sustain.
The specific date varies and the programme is informal enough that advance research will not help you much. The best approach is to arrive in August and ask. The festival's name — celebrating hospitality — gives you a sense of what to expect: not a spectacle, but an invitation into village life. For anyone travelling in the Ligurian interior in August, it is worth timing a visit around.
