Monti Sartorius Nature Trail

The Monti Sartorius Nature Trail is an easy circuit on the north side of Mount Etna, starting at Piano Provenzana in the comune of Linguaglossa, in the province of Catania, Sicily. The trail passes among the two craters formed during the 1865 eruption, named after the German geologist Wolfgang Sartorius von Waltershausen, who studied Etna in the nineteenth century. Access is by car from Catania in about 1 hour 15 minutes via Linguaglossa and the Mareneve road, as there is no regular public transport to Piano Provenzana. Parking is available at the ski-resort area, and no permit is normally needed for the low-altitude route. Italian Wikivoyage gives the length as about 4 km (2.5 miles), while another listing gives about 3.4 km, so walkers should rely on the trail markers and confirm details with the Parco dell'Etna. The loop takes about 2 hours and involves around 100 m of ascent, making it suitable for first-time hikers. The surface is a mix of dirt track, volcanic sand and cinder, with some uneven stretches over old lava. Parts of the route pass through birch and pine woodland, giving welcome shade, while the crater rims and open stretches are exposed to wind and sun. Landmarks include the two Sartorius cones themselves, the surrounding black lava fields of the 1865 flow, and views toward the upper slopes of Etna and, on clear days, the Ionian Sea. A natural turn-around point is the second crater, from which walkers can retrace the path if conditions worsen. Water is not available on the trail, so it should be carried from Piano Provenzana, where bars and shops offer drinks and shelter in season. The area also holds the ruins of buildings damaged by past eruptions, a reminder of the volcano's activity. Visitors should check the INGV bulletin and local ordinances, since alert-phase restrictions can affect access in the Etna Park.
