The thing is, with so much to see and do in and around Madrid, it isn't easy to get to see everything. The guided tours on this page allow you to see some of the cities around Madrid quickly and easily.

1. City Tour from Madrid: Seville and Cordoba (two days)
On the outward journeys, this trip is by coach. After half a day in Cordoba you are driven on to Seville, where you will sleep and have the whole following day to explore. Then you get the AVE train back.
If you've already been to Cordoba, or you're just not interested, there's a variation that takes you to Caceres instead: Seville and Cordoba from Madrid.
2. City Tour from Madrid: Segovia & Avila (one day)
3. City Tour from Madrid: El Escorial & Valle de los Caídos (one day)
This is the best combined tour on offer, for two reasons: (a) you don't need a day in each, so the compactness of the tour is ideal and (b) it is difficult to get to El Valle de los Caídos when trying to get there by public transport (you have to go via El Escorial and then there is only one bus per day that will take you all the way to the monument).
4. City Tour from Madrid: Toledo and Aranjuez
It is also possible to combined Toledo and El Escorial. This combines two of Madrid's most popular day trips into one, but it means you don't get to see El Valle de los Caidos (see above). I would take the tour that includes El Valle and then do Toledo separately, either this combined tour with Aranjuez or a Half-Day in Toledo.
