This full-day loop from Follina climbs the historic San Boldo Pass, threads five rock-hewn tunnels and drops to the wind-swept shores of Lake Santa Croce. Expect steep climbs, technical descents and rewarding views — plan for 2–8 hours depending on pace.

You crest the last hairpin and the road exhales — stone tunnels ahead cut into the rock like teeth, the valley below opening toward a sheet of glass where windsurfers tack off shore. This loop leaves Follina and climbs through Tovena onto the San Boldo Pass (≈700 m), riding the historic Strada dei Cento Giorni: five carved tunnels, tight switchbacks and raw, exposed limestone that demands attention and rewards with long descents.

Bring bike lights for tunnels
Tunnels on San Boldo are narrow and poorly lit; a strong front light and rear reflector are essential for safety.
Pace the climb
Use low gears and keep a steady cadence — the climb is sustained but manageable if you avoid redlining early.
Watch for crosswinds at the lake
Santa Croce is popular with windsurfers; gusts can be strong on exposed shorelines and affect bike handling.
Carry cash for small kiosks
Some village cafés and water stops may not accept cards — small bills make quick refueling easier.
Road or gravel bike
A well-maintained bike with reliable brakes and low gearing makes the climb and descents safer and more efficient.
Helmet and gloves
Protective gear is essential for the technical tunnels and fast downhill sections.
Front light and rear light/reflector
Tunnels are dark and sometimes narrow — lights increase visibility for you and oncoming traffic.
Hydration pack or bottles
Several long climbs and stretches without services make carrying water important, especially in summer heat.
