The Carpathian Loop: two weeks through Romania's mountains and citadels
This is the loop we keep recommending to friends: start in the royal resort of Sinaia, work through the castles and fortified towns of Transylvania, cross the Transfăgărășan, and finish with a few easy days in Bucharest. Two weeks is comfortable; it also compresses to ten days if you drop a night here and there.
When to go
July to mid-September is the safest window for the whole loop, because the Transfăgărășan is usually open and the mountain cable cars run on full schedules. June and late September are quieter and still work, but check the high road before you commit. Spring and autumn are lovely in the towns, though the mountain legs may be closed or foggy. Winter suits Sinaia, Brașov and Bucharest, not the full loop.
How to do the loop
A rental car is the easiest way to link the stops, picked up in Bucharest and returned there. Trains connect Sinaia, Brașov, Sighișoara and Sibiu, but not the Transfăgărășan or the smaller villages. Plan the long drives (Sibiu to Curtea de Argeș, and Curtea de Argeș back to Bucharest) for the morning, and avoid mountain roads after dark. Roads are good between the main towns, and slow in the mountains and in villages.
Sinaia (2-3 nights)
Peleș Castle is the headline and it earns it. Go on the first morning tour, before the buses, and pair it with the quieter Sinaia Monastery down the road. On the second day, take the cable car up toward the Bucegi plateau for Babele and the Sphinx if the weather is clear, or visit Cantacuzino Castle in Bușteni if it isn't. The gondola queues by 10am on weekends, so start early.
Râșnov and Brașov country (4-5 nights)
Base yourself around Râșnov. The citadel above town is a good half day, Bran Castle is twenty minutes away (go at opening time, it fills fast), and Brașov's old town deserves a full day on its own: the Black Church, Council Square, and the Tâmpa viewpoint if your legs are willing. Families should keep a day for the Libearty bear sanctuary at Zărnești (book a morning tour) or Dino Parc next to the citadel.
Sighișoara (1-2 nights)
The prettiest small town on the route. The clock tower museum and the covered Scholars' Stairs up to the Church on the Hill are the essentials, and the citadel itself is the pleasure: just walk it in the evening when the day trips leave.
Sibiu (2 nights)
Piața Mare and the Bridge of Lies are the postcard, but budget real time for the ASTRA open-air museum in the Dumbrava forest. It is one of the best ethnographic museums in Europe and needs at least half a day.
Over the Transfăgărășan to Curtea de Argeș (1 night)
Check the road is open first; it usually closes from late autumn to early summer. Leave early, stop at Bâlea Lake at the top, and take the serpentines slowly. The monastery at Curtea de Argeș, with its stone lace and the legend of Manole, is the reward on the far side.
Bucharest (3-4 nights)
Book the Palace of Parliament tour a few days ahead and bring your passport. Balance the heaviness with the Village Museum and a walk around Herăstrău lake, and keep one evening for the old town. Therme, the huge spa just outside the city, is the best rainy-day or rest-day plan in the country.
Shorter versions
For ten days, drop a night in Sinaia and one in Bucharest, and give Sibiu one night. For a long weekend, do Sinaia, Brașov and Bran only. If time is short, the Sighișoara and Sibiu stops are the easiest to shorten, since both are compact towns.
What to pack
Layers are the rule: the mountains are cool in the evenings even in summer, and the Transfăgărășan can be cold and windy at the top. Bring a rain jacket, walking shoes with grip for cobbles and trails, and a hat and sunscreen for the open plateaus. Churches and monasteries ask for covered shoulders and knees. Download offline maps, since mobile signal drops in the mountains.
Food worth planning around
Try sarmale (cabbage rolls), mămăligă with cheese and sour cream, ciorbă soups, grilled meats such as mici and papanași for dessert. Guesthouses often serve the best home-style meals, and mountain huts offer simple hot food with limited hours. Carry snacks and water on the long mountain days.
Common mistakes
Driving the Transfăgărășan without checking that it is open; arriving at Peleș or Bran at midday on a summer weekend; changing hotels every night; and planning the long drive days back to back. Leave a buffer for slow mountain traffic.
Before you go
Check entry rules for your passport and the opening days of every castle, museum and cable car, since many close on certain weekdays or for maintenance. Romania uses the leu, and cards work in towns, but carry some cash for villages. For shorter routes, see the Carpathian adventure and easy Romania itineraries.
