Etâr is best served from the nondescript city of Gabrovo, which has local buses (1 lv) for the 20-minute trip. Alternatively, take a Gabrovo–Kazanlâk bus and disembark at the turn-off near Lyubovo, from where it's a 2km walk. A taxi from Gabrovo costs about 10 lv. From Etâr, a taxi to Tryavna (25 lv to 30 lv) saves the trouble of bussing via Gabrovo.
Driving is more convenient, and Etâr makes a good day trip from Veliko Târnovo, Shipka or Tryavna.
