Yes, and it's a popular pairing, especially from Suceava. Voronet and Moldovita sit roughly 60-65 km (37-40 miles) away on winding mountain roads, and a custom-routed trip lets you set your own stops rather than follow a fixed tour schedule.
It's about 110 km (68 miles) from Suceava, 195 km (121 miles) from Cluj-Napoca, and 227 km (141 miles) from Iasi. The route climbs through Carpathian foothills with frequent curves, so travel times run longer than flat highway distances would suggest, generally 2.5 to 4 hours or more depending on the starting city and conditions.
A couple of hours cover the essentials: a walk through Central Park past the Sentinela mineral spring, then a ride up the chairlift. Most travelers pair the town with a nearby stop, such as a painted monastery, which a private day trip makes easy to fit into one itinerary.
The surrounding area adds outdoor variety: Calimani National Park's volcanic peaks and old-growth forest, and the Tinovul Mare peat bog near Poiana Stampei, about 20 km (12 miles) away, one of Romania's largest protected wetlands. Both suit travelers who want a nature stop alongside the spa town itself.
Vatra Dornei is Bukovina's historic spa town, set in the Carpathians where the Bistrita and Dorna rivers meet. Its 19th-century mineral springs, tree-lined Central Park, and mountain backdrop give it a different character than the lowland cities nearby, all reachable without committing to an overnight stay.
The Dornei chairlift. It climbs to around 1,268 m on Dealul Negru in about 25 minutes, opening up views over the Dorna Depression and the Calimani and Rodnei mountains. It runs seasonally and weather permitting, so it's worth checking current operating hours before your visit.
