Fair of la Castanya Activity · Viladrau, Osona, Girona Image of Viladrau, not of the place itself. Fair created in 1995 to recover the value of the main autumn product of the municipality. It is held on the last weekend of October, around Tots Sants, with sales of local produce, chestnuts roasted over the fire, tastings and guided visits to the chestnut groves.
