Home to the rare Lulworth Skipper and Berger's Clouded yellow, the Regional Park of La Brenne is fertile hunting ground for wildlife watchers. Having written about walking there elsewhere on this siteI am intrigued to note that specialist tour operatorNaturetrekis offering a butterfly spotting trip there, with a local guide who has access to private land. Expect to see blues, coppers, fritilleries and much more. it says. The park. which as not far to the east of Poitiers and roughly south of Tours, on the Loire, is known locally as "the land of a thousand lakes". It is also a great place to see water fowl. The trip departs on June 25 and costs from £995 for each of two sharing a hotel room and including rail travel from London and most meals.
