The Prado contains over 9000 paintings. (The museum attendants didn't know the exact number). Thus it is nearly impossible to see everything in one day and this was my second visit. I was actually the first visitor to enter the Prado on the day of my visit, because I knew from the last time to arrive even before the doors open at 9am because by 11am, it is not as pleasant to walk around with the hordes of people and it only gets worse as the day gets later.
Free floor maps come in Spanish or English and are well marked with directions along with the numbers of the rooms. Each room has the Roman numeral on the wall entrance to it. However I also chose to buy a floor plan book in the gift store for a more comprehensive visit. There are the typical souvenirs in the gift shop and I picked up another Prado book of paintings as well as some coasters, postcards and magnets.
In the Prado, the Spanish artists are probably the most famous, but there are also several paintings by Italian, Greek, French, Dutch, Flemish and other artists. I snapped a picture with a flash before I was gently reminded only pictures without flash may be taken. The photo came out with a big flash in the middle of the painting anyway. However, in some rooms there was enough light to take pictures without a flash and the magnificent El Coliseo de Roba can be seen below.
There are numerous temporary exhibits and lending of paintings to other museums going on at any particular time, so while I was fortunate to see some new paintings, I was also disappointed that some of my favorites from last time were on loan.
However, this time I discovered "Dauphin's Treasures" (or "Tesoros de Defin" in Spanish), in the basement and it should not be missed. I was also the only one down there at the time and enjoying a collection without having to look over others' shoulders makes a big difference. Yet even with people, this collection of delicately ornate cups, vases, plates, glasses and various types of stones, jewels and decorative arts would still be spectacular.
The only thing I recommend to skip is the cafeteria. After 3 hours in the Prado I was still not ready to leave, but I was also starving so I ate there. The food in the main cafeteria is buffet style and though you pay for everything separate there are no prices listed. Not only was the food unappetizing, but the section clearly marked non-smoking meant nothing as there were ashtrays on the tables and the whole room was smoky.
The Prado is spectacular but also eventually tiring and only a few of the rooms have benches in the middle where you can sit. However if you still have energy when you finish with the Prado, the magnificent Museo Thyssen-Bornemisza is just up the street.
