Yalova is a compact province on the southern shore of the Marmara Sea, roughly 90 minutes from Istanbul by fast ferry. Famous throughout Turkey for its therapeutic thermal springs centred on the spa resort of Termal, the city blends Ottoman-era pavilions, lush forests, long Black-Sea-adjacent beaches along the Armutlu peninsula, and a relaxed waterfront promenade. Its small size and excellent ferry connections make it an ideal weekend escape as well as a slower-paced base for exploring Bursa and the wider Marmara region.

Yalova has a humid subtropical climate (Köppen Cfa), moderated by the Marmara Sea. Summers are warm and humid with temperatures reaching 30–34 °C in July–August; winters are mild but rainy with occasional snow. Spring and autumn are the most comfortable seasons. The thermal springs make Yalova a year-round destination regardless of weather.
