One of the non-negotiable and must do activities in Opatija is to walk at least part of the way along the Franz-Jozef Promenade, a pedestrian-only path that runs along the shore from Volosko 3km to the north, or in the opposite direction to Lovran 6km to the south. Winding its way above rocky coves and passing the palm-sprouting gardens enriched with beautiful samples of cypress, oak and palm trees as well as ornate pre-World War I villas; the promenade offers fantastic views across the Kvarner Bay to Rijeka, with the lush Gorski Kotar mountains brooding in the background.
