On your day trip from Madrid, you'll stop at hilltop Los Cuatro Postes to admire superb panoramic views before visiting Avila's San Vicente Basilica. Tour also includes a visit to Avila's cathedral.

Ancient hill-top Avila has been declared a Unesco "Heritage of Mankind" city, and is famous for its intact city walls and 90 towers dating back to the 11th century. The city was the birthplace of the mystic writer Saint Teresa of Jesus (1515-82) and is an important pilgrimage site.

Next, it's on to Segovia to see one of the best Roman-era monuments on the Iberian Peninsula - Segovia's incredible aqueduct. Built in the time of Augustus, the aqueduct has 118 arches and is 10 miles (16 kilometers) long, although just a fraction of its length remains visible today.

Segovia is also famous for its Alcazar, a beautiful 11th-century medieval fort that inspired the design of the Disney castle. Step back in time and imagine the medieval tournaments that once took place and the heroic knights who fought here.

On this day trip you have the option of including a tourist-style lunch or superb gastronomic lunch featuring local Segovian specialties.
