Departure at the Alta
Valtellina bike village stadium in Rasin
Isolaccia;
Launch section passing
through the heart of the village of
Isolaccia;
Start uphill to Pedenosso Alto - S.Antonio tot. km 7
(5 km on asphalt and then beginning of dirt road);
Drop off on the little white road of the Decauville
turn right towards Torri di Fraele;
At Torri di Fraele mt 1930 (one of the most typical
connotations of Valdidentro, on the route of the ancient
Via Imperiale) you enter the spectacular valley of the
same name;
Passing near the small lake of Monte Scale, you reach
the Cancano dams, (two artificial lakes of enormous
dimensions that constitute an authentic work of
hydroelectric engineering inserted in an environment of
particular naturalistic interest; the hydroelectric use
of the Fraele valley dates back to 1928).
Follow the first dam on the left side, cross the
dividing wall and pass on the right side of the second
dam, over 12 km mostly flat on wide dirt road;
Once in the locality of S.Giacomo keeping to the
right you proceed on an easy path towards Val Mora near
the Swiss border ( we are still on the traces of the
ancient via d'Alemagna historical and important
commercial link between Valtellina and the neighboring
northern European countries until 1487). Before crossing
the border we turn and proceed in the direction of Prà
Grata to return to S.Giacomo.
Follow the S.Giacomo dam on the right side, after
about 3 km on a wide flat road, at Val Pettin, detour and
start the climb to Alpe Trela mt 2200, km 2 on a dirt
road with a compact bottom;
Short flat stretch and uphill again for another 1.5
km on path to reach Bocchette di Trelina mt 2283;
Spectacular descent in the direction of Val Vezzola:
first part on fun single-track and then continue on dirt
road to the entrance of the trail that goes to the
Foscagno valley; after a series of technical ups and
downs, descend and return to the flat Decauville road;
Passage at Arnoga, crossing the state road to Livigno
in the direction of Val Viola; a valley dominated by the
mountains that are part of the Cima Piazzi and Corna di
Campo group: in fact, the Cima Piazzi, Cima Viola and
Cima Dosdé soar above it;
A first uphill section km 1 leads into Val Verva;
At Baite Verva Bassa, on a newly created trail,
proceed on 3 km of fun ups and downs;
The trail becomes wider and after 1 km you pass
through Val Cardonnè and then turn left and after
crossing the bridge you climb for 500 m;
Flowing descent for 1 km
and detour right to Paluetta (ascent km 1);
From Paluetta km 1 on
varied terrain to Alpe Boron mt 2057;
Short descent and
immediately turn right to face a climb of about 1 km at
times very challenging "wall of Prei";
The trail climbs to Prei, a particularly scenic place
where the view can sweep over all the surrounding valleys
covered in the first part of the trail; through a new fun
flat path with a slight descent you reach Alpe Pone;
Still on a newly created path, we skirt the
Valdidentro alpine ski slopes to the entrance of the
Palancana road, a long flat stretch immersed in thick
pine forests among which spectacular panoramic windows
open onto the Bormio area;
Breathtaking descent to
the historic-naturalistic area of the Venini military
fort and the Paluaccio di Oga reserve;
Taking advantage of the fun trails built for the bike
park in Oga you "fly" to the Motte, the Corva, and with
passage on the winter cross-country ski trail and the
Isolaccia bike path you have arrived!
