These 2-sq-km protected wetlands were formed from 18th-century peat beds. A reed-fringed 4km walking path – partly on muddy tracks, partly on wooden walkways – encircles the water, which in late spring is dotted with water lilies.
A handy access point is at the southeast corner of the reserve, a few steps from San Pietro in Lamosa. There's a metered parking area here.
