We used this book for a trip to Umbria with our children ages 9 and 12 and thought it was great, both for the walking and the eating. We have been to Tuscany several times and wanted to branch out to Umbria on this last trip, and can only say we wish we had done so sooner. We stayed in the lovely town of Norcia, and did the "san Eutizio" walk: an amazing adventure with children! Norcia was an easy place to be with kids, the hotel recommended in the book was extremely friendly, the town had such a safe feeling and enough of interest (particularly the gelato bar) to the kids to keep them busy. The walk - one of the longer ones in the book - was an ambitious one for kids, but gave them an exceptional feeling of accomplishment at the end, and they loved the beautiful abbey at San Eutizio, especially enjoyable on our visit because as we ate dinner at the tiny restaurant next door (the only building in the immediate environs) there was a wedding going on, which spilled into the outdoors. While my husband and I lingered over our "vino," the kids went inside the abbey and mingled with the wedding party stragglers, a few of whom - along with our kids of course - crawled through an ancient tunnel behind the altar, an action that is supposed to cure all ills.
We also went up to Castelluccio, the mountain village about 15 miles from Norcia, which was stunningly beautiful, remote, and virtually deserted. There is a small restaurant there which was fabulous, and the sunset behind the austere Sibillini mountains was a stunning backdrop to our outdoor meal. Next time we would plan to stay in this tiny village overnight.
Note: we had the 2005 edition, and the friend who recommended this book says the san eutizio walk wasn't in the original.
