Transfagarasan North climbs from Cârțișoara into Romania's Carpathian Mountains on Route 7C - the legendary Transfăgărășan Highway, in the heart of Transylvania's Dracula country. The north side covers 29.4 km (18.3 mi) and gains 1,499 m (4,917 ft) at a 5.1% average grade, finishing near Bâlea Lake at roughly 2,000 m (6,561 ft), close to the road's highest point.
The road was built in 1971 on the order of communist dictator Nicolae Ceaușescu, as a strategic military route across the mountains in case of a Soviet invasion - which explains its scale: five tunnels, numerous viaducts, and around 30 numbered hairpins carry it up and over the range on a road far grander than the traffic it sees today. In 2009 the BBC's Jeremy Clarkson called it "the best road in the world" on Top Gear, and it's been on cyclists' bucket lists ever since.
Near the top, the road runs along the shore of Bâlea Lake, a glacial lake ringed by bare granite peaks, before reaching the Bâlea Tunnel - at 884 m, the longest road tunnel in Romania - which carries the highway through to the south side toward Curtea de Argeș.
Transfagarasan is often compared to Transalpina North, Romania's other legendary Carpathian crossing - many riders who visit one make a trip of both.

Transfagarasan North runs 29.4 km (18.3 mi) from Cârțișoara and gains 1,499 m (4,917 ft) at a 5.1% average grade, starting at 505 m (1,657 ft) and finishing around 2,000 m (6,561 ft) near Bâlea Lake.
The grade is remarkably even for a road of this scale - the steepest kilometer averages just 7.2%, and even the steepest quarter-mile only reaches 7.9%. There's no single brutal pitch to brace for; the challenge here is almost entirely about sustained distance and altitude, helped by long, engineered switchbacks that keep the grade rideable the whole way up.
Roadway: The road is paved and well-maintained for its entire length, with five tunnels along the way - bring a light. One PJAMM contributor, Anja, described them as no real obstacle: "No tunnels do not frighten me. I did not use a lamp. Tunnel on the top of a climb is narrow, only one car at once, like one way and then they stop and cars from opposite side... But lights are good so no problem, only a lot of dust inside so you need to be fast." The high section of this road - roughly from Bâlea Cascădă up to and over the summit - closes for winter every year, typically from late October or November until mid-to-late June depending on snowfall; the 2026 season reopened June 12. Check current opening status before planning a trip.
Traffic: Because it's one of the most famous roads in the world, Transfagarasan draws heavy car, motorcycle, and tour-bus traffic on summer weekends, especially near Bâlea Lake at the top where vehicles cluster around the cable car station and vendor stalls. Expect to share narrow hairpins with slow-moving tourist traffic and stay visible.
Parking: The climb starts in Cârțișoara, where informal roadside parking is available near where Route 7C passes Route 105P at the edge of the village.
Cârțișoara has basic services for fueling up before the climb, but there's little beyond it until Bâlea Lake at the top, which has a chalet, restaurant, and small shop - carry enough food and water for the full 29.4 km (18.3 mi) in between. Bring a light for the five tunnels along the way.
Standard road gearing is fine given the even grade, though a compact crankset makes the sustained climbing easier over this much distance and altitude. Temperatures at 2,000 m can be dramatically colder and windier than in the valley even in midsummer - pack a real jacket for the summit and the descent, not just arm warmers.

Bâlea Lake, near the top of this climb, has a cable car connecting it to Bâlea Cascadă below - it keeps running even when the road itself is closed for winter, and each year a Hotel of Ice is rebuilt from lake ice near the chalet, open roughly January through March. It's a genuinely different place to visit outside cycling season.
The Transfăgărășan's southern half - Transfagarasan South, from Buda toward Curtea de Argeș - is the other side of the same road and summit, and pairs naturally with this climb if you want to ride all the way over the mountains rather than out-and-back.
Base yourself in Sibiu, a well-preserved Saxon old town about an hour from Cârțișoara with a full range of hotels and restaurants, if you're spending more than a day in the area - it's also a reasonable staging point for Transalpina North on the other side of the range.
