From Madrid, Through the Peninsula
You've probably done a multi-day trip where every city got its half-day, the bus left on schedule, and by day four the cities blurred together. Nothing went wrong, exactly. It just stopped being a journey and became a sequence.
Madrid package tours run 3 to 15 days, through Castile, Andalusia, the Basque Coast, and Barcelona, with select routes into Portugal. Each city carries its own specialist — someone who's worked that ground for years — so the depth doesn't reset at the next hotel.
A multi-day trip should add up to something more than distance covered.
