The Three Chairs Basin, also known as the Târgu Secuiesc Basin, is located in the southeastern part of Transylvania in Romania and forms a prominent geographical unit within the Eastern Carpathians. It is bordered to the north by the Bodoc Mountains, to the east by the Nemira and Vrancea Mountains, and to the south by the Buzău Mountains. The basin landscape originated from tectonic subsidence and was shaped over time by the sedimentation of the Olt and Feketeügy (Black River) rivers. Climatically, the area is characterized by a moderate continental climate, with the basin location often leading to temperature inversions in winter. Historically and culturally, the basin is the heart of the Szeklerland, named after the three former administrative seats (chairs) that today form Covasna County. The region is famous for its numerous mineral water springs, locally referred to as 'Borvíz,' which reflect the volcanic past of the area. Economically, agriculture dominates, complemented by rising ecotourism in the surrounding mountain forests.

Getting there
The basin is generally reached via regional roads connecting the eastern border towns of Hungary and Romania. Surrounding municipalities provide good starting points for expeditions into the valley.
Best season
Spring and summer are highly recommended for exploring the basin, offering pleasant temperatures and clear views. Autumn also provides a spectacular display of colors against the backdrop of the Eastern Carpathians.
Terrain & paths
The valley floor is mostly flat and easy to navigate, contrasting with the rugged slopes of the surrounding mountains. Hiking trails vary from simple countryside walks to more challenging routes uphill.
What to bring
Comfortable walking shoes are sufficient for the basin floor, but proper hiking boots are needed for the surrounding peaks. Pack windproof clothing, as the open tectonic basin can experience sudden breezes.
Parking
Parking is typically available in the local villages or near designated scenic viewpoints along the main roads. It is usually easy to find a spot, even during the more popular travel months.
Safety
Travelers should prepare for sudden weather shifts that are common in basin areas surrounded by high mountains. Cell phone reception might be inconsistent in more remote sections, so downloading offline maps is advised.
Time needed
Exploring the main valley takes a few hours, while venturing into the surrounding Eastern Carpathians can take a full day. A half-day drive with frequent stops is a popular way to see the highlights.
