The Blue Lagoon: Krknjaši Bay, Plainly Located

Two famous blues share the Split boat boards, and travelers regularly book one wanting the other. This page exists to prevent that.

Where the Blue Lagoon actually is

Krknjaši bay, off the east side of Drvenik Veli island - about 14 nautical miles southwest of Split and 7 from Trogir. A shallow, sand-floored anchorage between islets where the water does its turquoise trick all day with no ticket, no queue and no light window. It is a swimming place, full stop - snorkeling over white sand, floating, lunch at anchor.

How it’s visited

Half-day speedboat runs from Split and Trogir (from about $64, typically with a Trogir old-town stop) and full-day “3 islands” cruises with lunch aboard (the 2,734-review all-inclusive is the format’s proven name, about $74). The season is kinder than the cave’s too: no cave closure variable, shorter sheltered runs, the family-friendly pick by a mile.

Lagoon or cave - the honest split

This site is about the cave - the 10–15 minute electric-blue spectacle on Biševo, earned by a full-day speedboat itinerary with a €24 ticket and a light window. The lagoon is the opposite proposition: hours IN the water, minutes reaching it. Kids, queasy stomachs, or swimming as the whole point: lagoon. The one image Croatia is famous for: cave.
