The Sile, with its nearly 100 km, is the longest resurgent river in Europe. It rises and flows to Casacorba di Vedelago (TV), about 15 km from Treviso. Its springs, locally referred to as “fontanassi”, are especially unique. There, a number of stream pools spring out from the clayey ground that forces the water out. The most famous resurgence pool is the Fontanasso dea Coa Longa, officially considered the spring of the river and marked by a large oak. The entire course is safeguarded by the River Sile Regional Natural Park. The river’s maximum width reaches 40 m and the water temperature has a low fluctuation from winter (+ 11/12°) to summer (+ 14/15°). The Sile was first mentioned by Pliny the Elder (Silis). Its name comes from the Latin word silen, which means silent, a clear reference to the river’s calm waters. Other theories suggest that it probably derives from a pre-Latin term (sila) that means canal, or that it has Indo-European roots (sel), with the meaning of spurting, emerging. April and May are the perfect months to visit the farms that produce the White Asparagus DOC in Badoere, while from October to March, the same farms offer the opportunity to see how the renowned Red Radicchio of Treviso is grown.
