I have been sent some details of these guided walks in Sicily - I know nothing about the company other than what I see on their website - but it looks tempting!
Spring Nature Walks in the Wonderful Madonia Park
For the second year, The Real Sicily is offering a Spring Nature Walks week in the Madonia mountains, Sicily’s first regional park, from May 11-18, 2019. Spring in the Madonia mountains, which rise to 6500 feet, is the most miraculous time of the year, with breath-taking displays of wild flowers, glorious bird song and some fascinating ancient trees. The Madonia are home to 50% of Sicily’s indigenous plants and 73 species of orchid.
This year’s guide, Marc Carlton, will lead a week of guided daily nature walks in diverse areas and botanical zones of the Madonia, the southernmost extension of Italy’s Appenine chain. On a series of medium-length group walks in a variety of habitats, Marc will be talking about the wild plants and insects en route and offering an insight into the ecology of this unique limestone range.
