You step off the riva in Split before dawn, the ferry horn sounding like a countdown. The Adriatic is a hard, clear mirror; limestone cliffs of the islands cut a serrated horizon. By mid-morning the boat trims toward Biševo and the water narrows until the cave mouth opens like a secret.

History
Vis served as a strategic naval base through Venetian and Austro-Hungarian rule and later as a restricted Yugoslav military zone; that history preserved many undeveloped shores. Hvar town’s harbor and fortress reflect a long Venetian maritime past.
Conservation
Several channels around the islands are part of sensitive marine habitats; avoid anchoring in posidonia beds, follow operator guidance, and take all litter off the islands.

Pack a lightweight wind layer
Wind can be brisk on open stretches; a thin jacket keeps you comfortable between swim stops and while cruising.
