Our first day we headed into Sinaia to see Peles Castle. If you follow the signs in Sinaia for the castle there is parking about half a mile up the hill from the castle grounds. It was about 2 euros to park for the whole day. There are two castles on the grounds Pelișor Castle and Peles Castle. Peles is more exquisite in design and architecture. You can join in on a tour, which is a large group of about 30 people, or do your own tour with audio guide in a small group. We chose the small group, as I hate being shuffled through rooms in a hurry. The rooms were filled with marble, glass and antiques galore. This was my favorite castle we visited on our trip. If you have time I highly recommend stopping by the Sinaia Monastery for a quick tour of one of the oldest churches in Romania. The area of Sinaia is a large ski resort town so when we were there in April it was pretty empty as the snow has nearly all melted. Walking from the Monastery down to old town was absolutely wonderful. All the carved homes along the road were a true depiction of Transylvania.
