The engine eases out of Gruž Harbor and the Adriatic opens — sun on steel water, the Elaphiti islets slipping past like punctuation marks. Within an hour the limestone cliffs of Mljet appear: green slopes, dark caves, and a coastline that invites you to choose a narrative — myth and monastery or quiet sand and salt lakes.

Carry local currency for fuel surcharges
A mandatory fuel surcharge is paid on check‑in and varies by boat type — have euros in cash to avoid delays.
Bring reef‑safe sunscreen and a hat
Sun and reflected light from the water intensify UV exposure during open‑water transfers and beach stops.
Waterproof bag for electronics
Short swims, spray, and quick hikes mean a dry bag keeps phones and documents safe while you explore.
Plan your swim/snorkel timing
Calmer seas mid‑morning and late afternoon are best for snorkeling and visibility; avoid swimming alone near cliffs.
