The Transalpina Road (DN67C), also known as the “King’s Road”, is the highest paved mountain road in Romania, reaching 2,145 meters above sea level at Urdele Pass. Crossing the Parâng Mountains, it offers cyclists a long, high-altitude climb through open alpine landscapes and some of the most remote terrain accessible by road in the Southern Carpathians.

Originally built by the Romans and later rebuilt during the reign of King Carol II in the 1930s, the Transalpina follows an old mountain route that has connected regions of Romania for centuries. Today, it remains one of the most impressive and demanding road climbs in the country, defined more by altitude and distance than by extreme gradients.

For cyclists, the most popular and classic ascent is from the south, starting in the town of Novaci. From here to Urdele Pass, the climb measures approximately 25 kilometers, with an elevation gain of around 1,600 meters. The average gradient is just over 6 percent, with the steepest sections reaching around 9 percent near the upper part of the climb. The ascent is long and steady, allowing riders to find a rhythm, especially once past the resort area of Rânca.

Another common approach is from Obârșia Lotrului, on the northern side of the high plateau. This side is shorter but still demanding, climbing steadily through open terrain toward the highest point of the road. Both approaches spend long stretches above the treeline, offering wide views and a strong sense of space.

The Transalpina is typically open only during summer, usually from mid-June until late October, depending on snow conditions. Because much of the road lies at high altitude, weather can change quickly, and temperatures near the top are often significantly cooler than in the valleys.

Facilities along the Transalpina are limited. There are no large restaurants at Urdele Pass itself, but during summer months small roadside stands may appear near Rânca and along the route, selling drinks, snacks, and simple traditional food. Riders should plan food and water carefully, especially on quieter weekdays when services may be minimal.

Traffic on the Transalpina is generally moderate, but weekends and public holidays can be busy, particularly in July and August. Early starts are recommended for cyclists who want a quieter experience and clearer views.

Cycling the Transalpina is about long effort, altitude, and open mountain riding. Its wide horizons and remote feel make it one of the most rewarding high-mountain roads for cyclists exploring Romania.
