Toast with oil and garlic and a big 'chocolatada' to whet your appetite. A good start to this spring festival. A market with artisans and food products, workshops for children, exhibitions, bouncy castles, music and giants all accompany this very traditional popular picnic. The star attraction of the day, however, are the free guided visits to the Lagoon of Pitillas
. The biggest natural lake in Navarre (216 hectares), it offers shelter to around a hundred bird species, including storks, geese, starlings, dippers and bee-eaters. A perfect occasion to enjoy the waters of this Natural Reserve.
