The Carmen Sylva forest path (Croatian: Šetalište Carmen Sylve) is a trail in Opatija, Croatia.
The forest path, which starts approx. 45°20'00.3"N 14°17'50.0"E and ends approx. 45°20'58.7"N 14°18'35.5"E, was originally called "King Carol's Forest Trail" (König-Carol-Waldweg). King Carol I of Romania came to Opatija in April 1896 and stayed in the Villa Angiolina [1] together with his wife Elisabeth (née Elisabeth of Wied), also known by her literary name of Carmen Sylva. King Carol I is said to have discovered the trail during a horse ride in the woods beneath Veprinac. A plaque today commemorates Baron Arthur Schmidt-Zabierow, the former district principal of Volosko, who constructed the path with funds donated by King Carol.
