Riserva Naturale Delle Salse Di Nirano hiking trails explore a unique landscape characterized by active mud volcanoes, known as "salse," which create a distinctive "lunar" terrain of grey earth mounds and mud flows. The reserve encompasses approximately 200 hectares of rolling hills, where the high salinity of the soil supports specialized salt-tolerant plants. This geological phenomenon is driven by rising seawater mixed with gaseous hydrocarbons, forming cone-shaped structures.

The most evocative part of the tour is undoubtedly the stretch of path that from "Cà Rossa" crosses (partly on wooden walkways also suitable for the disabled) the mud volcano area, which can be admired at very close range, obviously without touching anything! Since you enter a marshy area, equip yourself with adequate shoes, even boots might be useful if it has rained recently! The "short" tour that starts from the car park, reaches Cà Rossa via the "dragonfly path" and returns to the car park via the "owl path" takes about an hour.
