In various nature reserves around Nismes, a sub-municipality of Viroinval, we go in search of butterflies and special plants. We meet at 10:00 AM at the church of Nismes. From there we head to Tienne Breumont, Le Fondry des Chiens, Montagne-aux-Buis, Roche à Lomme … Op Le Fondry des Chiens we can easily picnic at noon. For those who want, there is the possibility to eat in the center of Nismes at the end of the trip, between 5 PM and 6 PM. Vanuit Lier is about 150km/2 hours drive. Registering is therefore easy to carpool.
