Over a third of Mljet is protected national park — a rare pocket of silence in the Adriatic where saltwater lakes, a 12th-century monastery on its own islet, and mongooses darting through the pines make for the most serene day in Croatia.
Most cruise ships tender at Pomena or Polače — both are small harbors inside or adjacent to the National Park.
💡 Pro move: Cash (€) recommended for bike rentals and small vendors; national park ticket offices also accept cards.
Mljet has no large cruise terminal — ships use the natural harbors at Pomena and Polače.

Mljet rewards active visitors — cycling the lake loop and the monastery boat are the signature experiences.
Rent a bicycle in Pomena and follow the flat, paved, car-free trail around Malo Jezero and Veliko Jezero. The forest is dense, the water shimmers through the pines, and the circuit takes 2–3 hours at a relaxed pace.
Find Mljet cycling tours →A solar-powered park boat crosses Veliko Jezero to the tiny islet of Sveta Marija, where a 12th-century Benedictine monastery stands with its Romanesque church and defensive tower. Ride is included in your park ticket.
Find Mljet monastery tours →Step off the pier in Polače and walk straight into the remnants of a 5th-century Roman palace — roofless walls, a residential block, and an early Christian basilica right on the waterfront. Free and unmissable if you land here.
Find Mljet history tours →The narrow channel connecting the two lakes creates a gentle tidal current. Jump in and drift from one lake to the other — the water is warm, emerald-green, and calm. The most popular swimming spot on the island.
Find Mljet swimming tours →A steep but shaded trail (about 45 min from Pristanište) leads to a fire watchtower at the top of Montokuc hill, with sweeping panoramic views of both lakes and the surrounding islands. Best for ships with a long port call.
Find Mljet hiking tours →In 1910, small Indian mongooses were introduced to eliminate the island's horned vipers. The snakes are long gone, but the mongooses thrived. Sit quietly on any forest path and you're likely to spot one darting through the undergrowth.
Find Mljet nature tours →The National Park's lakeside trails are flat, shaded, and perfectly suited for a cruise port visit.
Walk from the Pomena harbor through shaded pine forest along the shore of Malo Jezero to Mali Most, the narrow channel between the lakes. The current at the bridge is the island's most popular swim spot.

Transport options from the pier — taxis, shuttles, transit passes, and whether ride-share apps work here.
