On Saturday 16th there will be the choice of participating in one of three excursions. We will leave at 9:00 and return at about 19:00, depending on traffic and other events. A lunch bag will be provided as well as a short written guide of the visited site. Weather is unpredictable but usually that time of the year is still considered summer and we hope having good dry conditions with warm temperatures; in any case bringing a rain coat is convenient. There will be hikes of different length in the three sites but their difficulty is low: hiking shoes will be enough.
