Sa Calobra

Sa Calobra is a small village in the Escorca municipality on the northwest coast of the Spanish Balearic island of Mallorca.

The port village is a popular destination for coach trips and road cyclists. It is accessed by a single winding road, designed by Italian-Spanish engineer Antonio Parietti and opened in 1933, which features many hairpin bends and a 270° spiral bridge called the tie knot. The climb is officially called the Coll del Reis or the Coll de Cal Reis, the pass on 682 m altitude, though it is often referred to by the name of the village at its base and was built and is considered to be "as close as one could get to a perfect road for motorsport". Unconventionally the road was engineered with tourists in mind.
