Why Mljet Works for First-Time Kayakers
Mljet is a long, narrow island south of Korčula and northwest of Dubrovnik, about 37 km long and only around 3 km wide on average. Its western part has been a national park since 1960, covering roughly 53 square kilometres of forest, coast and sea. At the heart of the park are two lakes, the Great Lake (Veliko jezero) and the Small Lake (Malo jezero).
They are not freshwater lakes. Both are connected to the open sea through a narrow channel, so they hold seawater, but they are sheltered by wooded hills on all sides. That combination makes them unusually good for beginners: the water is salty and clear like the sea, yet usually calm, with no swell and no ferry traffic. Distances are short, the shore is always close, and there are places to land and rest.
The Two Lakes and St Mary's Islet
The Small Lake is the smaller and more enclosed of the two, a good place for a first half hour getting used to the paddle. It connects to the Great Lake under a short bridge known as Mali most. The Great Lake is larger and opens towards the sea through a channel on its southern side, which monks are said to have dug to link it to the sea.
In the Great Lake lies the islet of St Mary (Sveta Marija), with a Benedictine church and monastery founded in the late 12th century. Paddling out to the islet, landing and walking around it is the classic beginner route: a modest distance across sheltered water with a clear goal. Remember that tour boats also run to the islet, so keep an eye out for them near the landing stages.
Park Tickets and What They Include
You need a national park ticket to visit the lakes area. According to the park's 2026 price list, the entrance ticket includes one return boat trip to St Mary's islet, access to the park's inland sites, hiking on the marked trails around the lakes, parking at Vrbovica for day visitors, visitor insurance and the park's electric train. One-day tickets for adults, children aged 7 to 18 and students bought in the park for visits after 4 pm are reduced by 25 percent. Check the current prices on the park's official website, np-mljet.hr, before you go.
Kayak and bicycle hire is not included in the ticket. Rental operators work around the lakes and in the nearby villages during the summer season; agree on the price, the hire period and the area you may paddle before setting off.
A Simple Beginner Plan
Start early in the morning, when the water is calmest and the light is softer. Paddle the Small Lake first, pass under Mali most into the Great Lake, and head for St Mary's islet. After a break on the islet, return along the shoreline rather than straight across open water, so you are close to land if the wind picks up. Many visitors combine paddling with a swim; the lakes warm up in summer and are pleasant for swimming.
Avoid the channel to the open sea unless you are with a guide. Currents through narrow passages can be stronger than they look, and outside the lakes you are on open water exposed to wind and boat traffic.
Safety and Comfort
Wear a buoyancy aid, even on calm water. Take water, sunscreen, a hat and sunglasses; reflected sun on the water burns quickly. If you are new to kayaking, a sit-on-top or stable double kayak is easier than a narrow touring boat. Keep valuables in a dry bag, and leave anything you cannot afford to get wet on shore.
The afternoon breeze is common in summer, so plan longer outings for the morning. If you are uncertain, join a guided kayak tour: guides set the route, handle equipment and know the local conditions.
Getting to Mljet
The island is reached by ferry and catamaran. The car ferry from Dubrovnik-Gruž to Sobra takes about two and a half hours, while the faster catamaran takes roughly 90 minutes. Polače, inside the park, is also a stop for seasonal passenger lines. Pomena and Polače are the most convenient villages for the lakes. Timetables change between summer and the rest of the year, so check the current schedules before you go. Many visitors come on organised day trips from Dubrovnik or Korčula; staying overnight gives you the lakes early in the morning and in the evening, when they are quietest.
Croatia uses the euro. Carry some cash as well as cards, since small rentals and village cafés may not take cards.
