Spain - in 6 days - what to see?

[knclark]

My husband and I are going to Spain for the first time in a month. We only have 6 days to explore. We fly into Madrid. We plan to head to Barcelona. But would love to see Valencia, Granada, Seville, Toledo. But I know we won't have time for all these on this trip.

We love to try foods, explore, hike, see cool things.

What are MUST sees / Cool things to see and do in Spain.

What should we avoid or skip?

TIA!
