Lago Lao e Monte Castello di Quarzina – loop hike

Embark on the Lago Lao e Monte Castello di Quarzina loop hike, a difficult 7.7-mile (12.4 km) journey with a significant 3083 feet (940 metres) of elevation gain, typically taking around 5 hours and 26 minutes to complete. This challenging route guides you through varied terrain, from asphalt and dirt roads to natural mule tracks and rocky slopes. You will traverse beautiful beech and pine forests before reaching the serene Lago Lao, nestled at approximately 1570 meters. The ascent to Monte Castello di Quarzina offers panoramic views, sometimes extending all the way to the sea, while the descent can involve unstable scree sections. Expect a diverse landscape that keeps you engaged throughout this demanding hike.

This difficult loop demands good physical conditioning and sure-footedness, especially on the ascent to Monte Castello di Quarzina and the potentially unstable rocky sections during the descent. While challenging, the trail is particularly recommended for the half seasons of spring and autumn, when the natural beauty is at its peak. You can even enjoy this hike in winter, though conditions will naturally be more demanding. Be prepared for varied path types, including alpine hiking trails, general trails, and some road sections. Always pay careful attention to signage, as some parts of the route are less evident.

What truly sets this trail apart is the unique naturalistic highlight of Lago Lao, which hosts one of the northernmost colonies of Alpine newts (Tritoni alpestri). Beyond this ecological gem, the route also takes you across the beautiful plain of La Colma (Pian della Colma) at 1515 meters, where you can find the charming Chapel of San Giovanni Battista. This blend of challenging alpine hiking, diverse scenery, and distinct natural features makes the loop a comprehensive experience of the mountainous landscape.
