From Korfu to Saranda (all year) or Himara (in summer), then take the bus to Jal. Or from Italy Bari, Brindisi to Vlorë and Durrës, than take the bus in the direction to Saranda or Himara.

While travelling along the Albania Riveria, many folks are willing to give you a ride to your next beach town. A small donation at the end (200-400 LEK) is a nice gesture and much appreciated by locals.
