Three medieval towns, two famous castles and a handful of Saxon villages with fortified churches — all of it fits into a Transylvania loop of roughly 750 km, done comfortably in 5 days. It is probably the easiest road trip in Romania: short distances, good roads and something to see at every stop.
By car, Transylvania joins up naturally. By train you would change three times and miss the villages, which have no station anyway. Here is a concrete itinerary, with real distances and one trap to avoid.
Day 1: Bucharest – Brașov, up the Prahova Valley
From Bucharest to Brașov is about 170 km, 2.5–3 hours on DN1, through the Prahova Valley. Stop in Sinaia for Peleș Castle, the most spectacular castle in Romania, and perhaps at Bușteni too. One trap to know from the start: on summer and winter weekends, DN1 through Prahova gets seriously congested. Leave at first light, or plan to come down on the way back rather than on the way up.
Settle into Brașov, a handsome town that is easy to walk: Piața Sfatului, the Black Church, the old lanes.
Day 2: the castles around Brașov
Keep the car close, because today is all short hops. Bran Castle is ~30 km from Brașov (45 minutes) — the one tourism ties to the Dracula legend. On the way, stop at Râșnov Citadel, ~17 km out, with a fine view over the area.
If you want something less trodden, climb up to one of the Saxon peasant citadels nearby. Back to Brașov for the evening. It is a relaxed day, designed so you do not drive much.
Day 3: Brașov – Sighișoara
Sighișoara is ~120 km from Brașov (~2 hours) on DN13, through Rupea and Saschiz — good roads with Saxon villages along the way. Stop at Rupea Citadel and, if you feel like it, at the fortified church in Saschiz.
Sighișoara is the only inhabited medieval citadel in Europe: the Clock Tower, cobbled lanes, coloured houses. It is small — an afternoon and an evening covers it, and it looks best at sunset.
Day 4: Sighișoara – Sibiu
From Sighișoara to Sibiu is ~90 km (1.5 hours), via Mediaș. On the way you can turn off to Biertan, one of the most impressive fortified churches in Transylvania.
Sibiu is arguably the prettiest town on the loop: Piața Mare, Piața Mică, the Bridge of Lies, the "eyes" set into the rooftops. Walk it without hurrying and eat well — the food scene is surprisingly good.
Day 5: Sibiu – Bucharest
You close the loop. From Sibiu to Bucharest you have two options: through Vâlcea on A1 and DN7, about 275 km (4–5 hours), with Cozia Monastery on the way; or back through Brașov, somewhat longer. The first is more direct and less busy.
If you have a spare day and it is summer, you can add the Transfăgărășan to Sibiu — but that is a road in its own right, with its own season.
In short
- Total: ~750 km, 5 unhurried days.
- Day 1: Bucharest–Brașov (170 km), with Peleș on the way.
- Day 2: Bran (30 km) and Râșnov (17 km) from Brașov.
- Day 3: Brașov–Sighișoara (120 km), through the Saxon villages.
- Day 4: Sighișoara–Sibiu (90 km), with Biertan.
- Day 5: Sibiu–Bucharest (275 km, via Vâlcea).
- Trap: DN1 through Prahova clogs up at weekends — leave early.
A loop like this works best with the car picked up on arrival, straight from Otopeni, so you can set off for Brașov the same day. Unlimited mileage means you can take every detour through the villages without watching the odometer. If your flight lands at Băneasa, you set off from there for 15€ per leg instead of 20€.
