Best day trips from Dubrovnik: 10 things to do

Lokrum, the Elafiti Islands, Mljet, Cavtat, Montenegro, Mostar, and Pelješac wine — independent boat, bus, and optional hire-car days from Dubrovnik.

Dubrovnik’s Old Town sits on the edge of a coastline stitched together by short ferry hops, island archipelagos, and a couple of genuinely ambitious cross-border runs. Lokrum is a ten-minute boat ride from the Old Port, the Elafiti Islands and Mljet National Park are a scenic ferry away, and Montenegro’s Bay of Kotor and Bosnia’s Mostar are both doable as long but rewarding day trips if you plan around border crossings. This guide covers the independent (DIY) version of each route. For hotel-pickup packages that handle the transport and border logistics for you, see the companion Dubrovnik day trips with guided tours. Pair either approach with the Dubrovnik destination guide for where to base yourself in the city.

How to day-trip independently from Dubrovnik

Do not plan around a hire car for anything inside the Old Town. Dubrovnik’s walled historic center is entirely pedestrian — no cars are permitted inside the city walls, and the narrow limestone-paved lanes were built centuries before anyone imagined a vehicle would need to fit through them. For trips that run on a local ferry or catamaran (Lokrum, the Elafiti Islands, Mljet, Korčula), skip the car entirely and walk down to the Old Port or the Gruž ferry terminal instead. A hire car earns its keep on a specific set of routes: the Pelješac peninsula’s wine roads and Ston’s oyster beds, a Konavle valley loop, and — for confident drivers comfortable with a border crossing — Montenegro’s Bay of Kotor. Mostar in Bosnia is usually better as a long coach transfer or guided day trip than a self-drive, since it adds a second border crossing and several hours each way.

• Book Elafiti and Mljet ferry or catamaran tickets a day ahead in July–August, when sailings fill up on short notice
• Carry a passport or national ID for Montenegro and Bosnia — both border crossings can involve real queues in peak summer
• Wear proper walking shoes — Dubrovnik’s Old Town lanes, Lokrum’s trails, and Mljet’s park paths are all uneven stone or dirt underfoot
• Bring cash for small island cafés and the Ston oyster stalls, where card acceptance is inconsistent

1. Lokrum Island

Small boats leave the Old Port roughly every 30 minutes in season and reach Lokrum in about ten minutes, making it the easiest and shortest trip on this list — genuinely doable as a half-day. The island is a nature reserve dense with pine and holm oak, home to a ruined Benedictine monastery, a saltwater lake nicknamed the Dead Sea, and a resident colony of peacocks that wander the paths without much concern for visitors. It is also where parts of Game of Thrones’ King’s Landing scenes were filmed, and a small “Iron Throne” replica draws a steady trickle of fans.

2. Elafiti Islands (Koločep, Lopud, Šipan)

Local ferries and seasonal catamarans from Gruž harbor reach this string of car-free islands in 30–90 minutes depending on which one you choose. Koločep is the closest and quietest, with sandy coves and pine-shaded paths; Lopud has a long, gently sloping sandy beach at Šunj that is unusually good for swimming with kids; and Šipan, the largest, has a scattering of old stone villas and a slower, more rural pace. Many day-boat tours stop at two or three of the Elafitis in a single outing, but the local ferry lets you pick just one and settle in for the day.

3. Cavtat

A short ferry or bus ride south of Dubrovnik — about 30–45 minutes each way — brings you to Cavtat, a quieter, more low-key harbor town on its own small peninsula. The seafront promenade, backed by cypress trees and a scattering of Baroque-era villas, makes for an easy half-day, and Cavtat’s more relaxed pace is a genuine contrast to the Old Town’s summer crowds. It also works well as a first or last stop before or after a flight, since Dubrovnik Airport sits just up the road.

4. Mljet National Park

A catamaran from Gruž harbor to Mljet takes around 1.5–2 hours each way, so this is a genuinely long day, but the payoff is one of Croatia’s most striking national parks: two interlinked saltwater lakes ringed by pine forest, with a small islet in the larger lake holding a 12th-century Benedictine monastery reachable by a short boat shuttle. Rent a bike at the park entrance to circle the lakes, or simply swim in the warm, still water — either way, budget the whole day and check the last return sailing before you set off.

5. Korčula

Korčula sits further up the coast, and a direct catamaran from Dubrovnik takes roughly 2.5–3 hours each way in season — an ambitious but manageable day if the sailing times line up. The walled old town, said by local tradition to be the birthplace of Marco Polo, is a smaller, quieter echo of Dubrovnik’s own historic core, with a fish-bone street layout designed to funnel sea breezes through town and block harsh summer sun. If the ferry schedule only allows a few hours on the island, prioritize a walk around the walls and a glass of local Pošip white wine over trying to see everything.

6. Montenegro and the Bay of Kotor

The drive south to Montenegro’s Bay of Kotor takes about 2–2.5 hours each way by road, crossing the Croatia–Montenegro border, so bring a passport or national ID and expect queues in peak season. The bay itself, often compared to a Mediterranean fjord, winds between steep mountains and a string of old stone towns — Kotor’s walled old town and its fortress walk up the mountainside are the main draw, and many day trips also add a stop at Perast, a tiny Baroque harbor town with a boat-accessible islet church just offshore. This route works as a self-drive if you are comfortable with the border crossing, but the distance and paperwork make it one of the better candidates for a guided day tour instead.

7. Mostar, Bosnia and Herzegovina

Mostar is roughly 3 hours from Dubrovnik by road each way, crossing into Bosnia and Herzegovina, which makes this the longest and most demanding trip on this list — realistically 6+ hours of travel for a few hours on the ground. The reward is the reconstructed Stari Most, the 16th-century Ottoman stone bridge (rebuilt after being destroyed in the 1990s war) that local divers still leap from into the Neretva River below, plus a walkable old town of cobbled lanes, mosques, and craft stalls. Given the distance and a second border crossing, most travelers find a long-distance coach or a guided day tour less stressful than self-driving.

8. Pelješac Peninsula wine roads and Ston oysters

A hire car genuinely earns its keep here: the Pelješac peninsula begins about an hour north of Dubrovnik and is Croatia’s best-known wine region, home to the bold red Dingač and Postup varietals grown on steep, sun-baked slopes above the Adriatic. En route, stop in Ston, famous for its oyster and mussel beds in the shallow Mali Ston bay and for the Walls of Ston, a lesser-known but genuinely enormous defensive wall system that once rivaled the Great Wall of China in scale relative to its era. A slow day of vineyard stops and a fresh oyster lunch in Ston makes this one of the more relaxed options on this list.

9. Trsteno Arboretum

A short drive or local bus ride north of Dubrovnik — about 30 minutes — reaches Trsteno, home to one of the oldest arboretums in Europe, planted by a noble Dubrovnik family in the 15th century. Centuries-old plane trees, a Renaissance aqueduct-fed fountain, and terraced gardens overlooking the sea make this an easy, low-effort half-day, and its cinematic gardens (also used as a Game of Thrones filming location) reward even a short visit without needing a full day set aside.

10. Konavle Valley

South of Cavtat, the Konavle valley is Dubrovnik’s green, agricultural hinterland — rolling fields, stone villages, and the spring-fed Ljuta River, which powers a handful of old watermills that have been converted into rustic riverside restaurants. It is best explored by hire car or a short guided countryside tour, and pairs naturally with a stop in Cavtat on the way back, making it a good half-day option for travelers who want a slower, rural contrast to the coast.

Self-drive vs guided day trips

Choose DIY for Lokrum, the Elafiti Islands, Cavtat, Mljet, and Korčula — all run on direct local ferries or catamarans from the Old Port or Gruž harbor with straightforward tickets. A hire car is genuinely useful for Pelješac’s wine roads and Ston, and for a Konavle valley loop, where public transport is thin and your own schedule matters more than the destination itself. Lean toward a guided tour for Montenegro and Mostar, where the distance, a border crossing, and unfamiliar paperwork make a driver or coach genuinely easier than self-driving. If you are building a longer visit, see the 3-day itineraries for how these routes fit around a fuller stay, and pair either approach with the Dubrovnik destination guide for where to stay.
