Aranjuez is my favorite royal palace, and this is my second favorite. I loved the tapestries and the explanations about them in the audio guide was really good. There were more unique elements in this palace than I expected, especially the bottom floor. But that area is really cold and the building isn't heated to plan on keeping warm and keeping your gloves and jacket on! The gardens I'm sure are beautiful, but we went to late in the year to enjoy them. I would recommend to visit it if you have the time, but it is a little out of the way if you're trying to see Segovia too so I would stick with Segovia over making the trek to La Granja. However, if you're headed to La Granja from Segovia or vice versa, there is a bus that will take you there and it comes pretty regularly so make sure to check that to keep from paying expensive taxi fares!
