Bonassola - San Giorgio - Gronde - Passo del Colletto

The itinerary follows one of the historic vertical connections between the coast of Bonassola and the mountain watershed towards Levanto. The route starts from the coastal village of Bonassola and initially develops along an old cobbled and stepped mule track climbing among terraced olive groves. After reaching the evocative hillside hamlet of San Giorgio, located at approximately 150 metres above sea level and known for its historic church, the trail enters a denser rural and woodland environment and passes the scattered houses of Gronde. From here, the path climbs more steadily and decisively among maritime pines and Mediterranean scrub, offering notable panoramic views over the bay below. The hike ends at the 465-metre elevation of Passo del Colletto, also known simply as “Il Colletto”, a strategic pass where the routes towards the summit of Monte Rossola, the descent to Levanto via Lavaggiorosso and the trails heading towards Dosso and Framura converge.

• Wear stable hiking boots with a lugged sole: sections of the stone mule track may become slippery in high humidity or when covered with dry leaves.
• There are no reliable drinking-water sources along the mountain section. Refill completely before departure in Bonassola or in the hamlet of San Giorgio.
• After rain or recent thunderstorms, take care on the unpaved section between Gronde and Passo del Colletto, where muddy segments or unstable rocks may occur.
