The Dalmatian archipelago holds 1,244 islands, yet fewer than seventy are inhabited.
Most visitors to Split never leave the Riva promenade, unaware that a thirty-minute speedboat ride separates them from the Blue Cave on Biševo, where morning sunlight refracts through an underwater opening to paint the cavern walls in electric cobalt. The cave was known to local fishermen for centuries, but its entrance was widened by Austrian naturalist Baron Eugen von Ransonnet in 1884, turning it into a navigable wonder. Today it anchors the most popular Split island hopping day trip itineraries, typically paired with Vis, Hvar, Pakleni Islands, and the Blue Lagoon near Drvenik.
These routes rose to prominence after Croatia joined the European Union in 2013 and Vis opened to tourism following decades of military restriction. The island served as a Yugoslav naval base until 1989, and its isolation preserved stone villages, Tito's bunkers, and underwater visibility that divers compare to the Maldives. Speedboat operators began linking Vis to Hvar and the Blue Lagoon in the mid-2010s, creating a circuit that delivers five distinct landscapes in eight hours. Hvar Town retains its Venetian loggia and Renaissance cathedral, while the Pakleni Islands offer deserted coves accessible only by boat. The Blue Lagoon itself is a shallow bay between three islets, where the seabed is pale limestone and the water temperature reaches twenty-four degrees Celsius by June.
Departures run daily from Split's Riva waterfront between April and October, with morning slots departing at 08:00 to reach the Blue Cave before midday crowds. Speedboats carry twelve to eighteen passengers, reducing transit time compared to larger ferries. Most itineraries include swimming stops at Stiniva Cove on Vis and Palmižana Bay in the Pakleni chain, both sheltered by karst cliffs. Operators provide snorkelling gear and life jackets, and guides speak English, German, and Italian. The Blue Cave charges a separate entrance fee of seven euros, collected on-site, while the Blue Lagoon and beaches remain free. Return to Split typically occurs by 17:00, allowing evening time in the city.
Island hopping tours from Split now account for thirty percent of the city's summer tourism revenue, according to the Split-Dalmatia County tourist board. The format suits travellers with limited time who want to sample the archipelago without booking individual ferries or overnight stays. Weather permitting, the speedboat circuit operates six days a week, with Monday departures sometimes suspended for boat maintenance. The season peaks in July and August, when advance booking is necessary, but September offers calmer seas and lower prices.
