Arrive at Bucharest, drive north, see Lake Snagov where Vlad Tepes was said to be buried in part at the monastery there; and then Sinaia. Peles Castle.
Sinaia. It is a prime ski area, great resort, and there is a splendid castle. A fine video of Peles is at http://www.youtube.com/watch?v=fq9O9ecRVlM&feature=related/. For photos and surroundings at http://www.montania.ro/en_vile.
Beware of claims to a Vlad Tepes connection. The castle, Peles, has no connection to Vlad that I can find, but this site suggests by its name that it does - http://www.draculascastle.com/html/pelesint.
Peles was built, instead, by King Carol I during a period centuries after, in the 19th Century, 1873-1883. See http://www.infotravelromania.ro/en/castle. Still, it is magnificent, and the photos at the infotravel site include other castles - worth a look. See also http://visit.peles.ro/the-history-of-the-peles-castle/
Carol I, King Charles I.
The town has all the shops and cafes you would expect. We don't shop, we people-watch and this was excellent for that.
