But here I am contradicting myself to describe a stretch of the Blue Trail (No. 2 numbering CAI), namely that between Corniglia and Vernazza, route today (October 30, 2008) to accompany Working class boys 3rd of SM Monterotondo tour operator customers of mine of La Grande Travel . With
me another colleague, Marco with whom we shared the path dividing the classes.
Description of the route










Length: 4 km
Key Quote:
- railway station 10 m above sea level
- Corniglia S. Pietro 95 m s.l.m.
- Punto panoramico 160 m slm-Punto sosta c/o frana di Guvano 155 m slm.
- Prevo 208 m slm-Vernazza 4 m slm
Fruibilità: questo tratto di sentiero, come tutto il sentiero litoraneo n° 2 che collega tutti e cinque i borghi, è percorribile previo pagamento di un biglietto di acceso (vedi le diverse tipologie di CARD 5T ); i ricavati sono utilizzati tra l’altro per la manutenzione dei percorsi e il ripristino dei muretti a secco. Il lieve dislivello e le condizioni del fondo lo rendono adatto quasi a tutti; qualche problema potrebbe averlo chi soffre di vertigini per alcuni tratti esposti ma comunque protetti parapet.
Fund features: location almost completely paved with stone, with traits at the landslides of Guvano of dirt road, wooden steps just before the landslides of overcoming a difficult (note the steps slippery in the rain!). Due to the large turnout of walkers, over time it was noticed some erosion of certain sections.
signs and emergency services : once the route was marked by a trail white / blue; today that these signs are a few tracks, replaced by more appropriate signage CAI. A new feature consists of several tables placed along the path traveled with emergency numbers and useful information for locating the point in an emergency
. The posts emergency solar-power related to operating 118-115-1515 are present and active for some years.
Criticality and jarring notes: considering the great turnout on the trails during the warmer months and especially during the holidays, attention should be given to persons making





presence of drinking water: Corniglia to find several public fountains, three near the church, all with excellent water. At the landslides of Guvano do not count on small spring almost always dry. A Prevo there is a bar open seasonally (summer and holidays, not all). Vernazza also found a couple of public fountains.
Prevo : small group of houses along the hillside (208 m) which meets about half way along the path . Some local historians have speculated for Prevo very ancient, if, even in etymological basis, even Roman origins. According to these scholars Prevo would rise as the old station to stop and change horses in the service of the ancient Via Littoranea. Unfortunately, only a hypothesis, although attractive, are not substantiated by historical documents.
Historical Notes on the geology and landslides of Guvano
The competition generated by landslides is of particular geological conditions: the contact between two different geological units (units and Tuscan Units Canetolo) tectonized strongly, the presence of a aquifer, the particular composition of the unit and LOCATION Canetolo. Both are composed of sedimentary rocks, but as the units are Toscane rappresentate in questo trato di costa da solide torbiditi arenacee, l’Unità di Canetolo è costituita da argilliti, brecce calcaree, calcareniti, calcisiltiti, che oltre ad essere fortemente alterate tai movimenti tettonici, sono per loro natura soggette ad assorbire l’acqua, aumentando di volume e assumendo una consistenza plastica, tutti fattori che contribuiscono a innescare fenomeni franosi.
Le cronache raccontano come la notte fra il 26 e il 27 dicembre 1853 un’enorme massa di rocce e terra si mise in movimento appena sotto il borgo di San Bernardino colassando in mare dove ancora oggi è possibile osservare il caratteristico fronte di frana aperto a ventaglio sulla costa. Cesare Zolfanelli e Vincenzo Santini descrissero la Help each other in the Alps in 1874: " pressure piled at the foot of the cliff materials confusedly, that was obviously some rough boulders, underwater rocks, which formed in front of the small breast Guvan, were driven from the bottom up and emerged covered with corals and coral that for a trato found themselves in a deadly element to them "
The landslide has never stopped completely so that the first track to single track railway line had to be periodically realigned due to the slow movement of soil that tends to drag towards the sea. Around 1960, when the doubling of the line, it was decided to pass the path ni gallery, finally leaving the path open. Today, facing the path, you can see the bottom of the valley Guvano the beginning of the two abandoned tunnels and a glimpse of the old layout

Flora and vegetation the path is characterized by olive trees, sometimes in a state of neglect. They are kept turfed and bloom from spring are characterized by 'yellow wood sorrel (Oxalis pes-caprae) una pianta alloctona ormai naturalizzata, con un temperamento decisamente infestante.
Degna di nota la presenza nei pressi della paleofrana di un endemismo, l’euforbia spinosa ligure (Euphorbia spinosa subsp. ligustica) che normalmente vive sui substrati ofiolitici. Da Prevo a Vernazza ancora uliveti ma anche macchia mediterranea e tratti a vegetazione rupestre. Spiccano in questi ambienti le grandi infiorescenze delle agavi.
Segnalazione faunistiche: in questo tratto si osserva spesso il più grande passeraceo europeo: il corvo imperiale (Corvus corax) it has a wingspan that can reach 1.3 m. In Italy it is present with populations rather than localized, and is not often meet.
actors and performers: the guys here MS Monterotondo, his face covered for privacy reasons (!?)... hello guys, you were nice! Greetings also to the teachers and the carer Michele DIMAV Italy, having a nice enthusiastic love with a beautiful slate could not do so entirely at less than " camallarsela " all the way! Ebbravo, greetings to you too! And finally, Mark, my colleague Guide, represented here as it emerges as a shoot of asparagus by vegetation, greetings to you too!
