Four Headwaters Trail

This loop run is classified as difficult. While some sections around Lake Lucendro might be on good gravel roads, the overall route includes significant elevation changes and technical, rocky mountain paths. It requires good fitness, sure-footedness, and sturdy shoes, making it suitable for experienced trail runners.

The terrain is diverse. You'll encounter good quality gravel roads and some paved stretches, particularly near Lake Lucendro. However, other parts, especially leading to higher passes, feature rocky mountain paths, steeply sloping sections, and areas with uneven rocks that can be exposed or slippery, particularly after rain. Some sections will likely require walking due to their technicality and steepness.

You can typically find parking near the San Gottardo Pass (Passo di San Gottardo), which serves as the starting point for this loop. Look for designated parking areas around the Ospizio San Gottardo.

Yes, the starting point at San Gottardo Pass is generally accessible by bus during the operating season. Check local bus schedules for routes connecting to Passo di San Gottardo.

The route offers stunning alpine scenery. You'll pass by several alpine lakes, including Lake Lucendro, Laghi della Valletta, Laghi d'Orsirora, Lago d'Orsino, and Lago della Piazza. Other notable features include the impressive Lucendro Dam, the rugged high-altitude landscape, and views of the historic Tremola road from certain vantage points.

The best time to undertake this loop run is typically during the summer months (July to September) and early autumn. During this period, the snow has usually melted, and the weather conditions are more favorable for high-alpine trail running. Always check the local weather forecast before you go, as conditions can change rapidly in the mountains.

While dogs are generally allowed on trails in the Swiss Alps, it's important to keep them on a leash, especially in areas with grazing livestock or protected wildlife. Given the technical and rocky nature of parts of this trail, ensure your dog is accustomed to such terrain and that their paws are protected.
