Summer is Europe’s best season for long days, open-air dinners and swimming in lakes and seas. It’s also the busiest and, in the south, the hottest. These 12 trips balance the two, mixing cooler northern and Alpine escapes with Mediterranean classics that still work in a long weekend.
1. Lucerne and its lake, Switzerland
Lucerne sits at the edge of a fjord-like lake ringed by mountains, with the wooden Chapel Bridge and Water Tower at its heart. Summer is the time for lake steamers, swims from lakeside lidos and hikes on Rigi or Pilatus, where the air is fresher than in the valleys. The Swiss rail network makes it easy without a car.
Best for: mountain views and lake swims without the drive.
2. The Salzkammergut, Austria
A region of clear Alpine lakes east of Salzburg, including Hallstatt, part of a UNESCO World Heritage cultural landscape. Hallstatt gets very busy in summer, so stay nearby and visit early or late. Wolfgangsee, Traunsee and Altaussee are calmer bases for swimming, boating and walks.
Best for: lake swimming and classic Alpine villages.
3. Copenhagen, Denmark
Copenhagen comes alive in summer, with long light evenings, cycling everywhere and swimming spots in the harbour itself. Mix the old canal-side quarter of Nyhavn with the city’s parks and a day trip along the coast to the north.
Best for: a cool-climate city break with a swim.
4. The Mullerthal, Luxembourg
Nicknamed Luxembourg’s Little Switzerland, the Mullerthal is a landscape of sandstone gorges, mossy forests and small streams. The waymarked Mullerthal Trail runs for 112 km across three main routes, so you can walk a single loop in a day. Base yourself in Echternach, Luxembourg’s oldest town, and combine it with an evening in Luxembourg City.
Best for: shaded summer hiking close to a capital.
5. The Wadden coast and Texel, Netherlands
Texel is the largest of the Dutch Wadden Islands, a short ferry crossing from Den Helder in North Holland. Expect long sandy beaches, dunes, cycling paths and seal-watching. Summer temperatures stay mild, and the sea breeze keeps it comfortable.
Best for: easy beach cycling and wide-open skies.
6. Berlin and its lakes, Germany
Berlin in summer is all about the outdoors: beer gardens, open-air cinemas and lakes such as the Wannsee and Müggelsee within reach by S-Bahn. Spend a day on the city’s history and art, then cool off at a lake beach. Read our Berlin guide to plan the city half.
Best for: a city break with a lake swim.
7. Český Krumlov and South Bohemia, Czechia
Český Krumlov wraps around a bend in the Vltava, with a castle above its old town. Summer is the season for rafting or canoeing gentle stretches of the river. Combine it with a couple of nights in Prague, using our Prague over a weekend guide.
Best for: river trips and a fairytale old town.
8. Split and the Dalmatian islands, Croatia
Split’s old town is built inside a Roman emperor’s palace, and ferries and catamarans connect it to islands such as Brač, Hvar and Vis. Choose one island for a weekend rather than hopping too much. The water is clear, and the swimming is good from rocks and coves.
Best for: island-hopping and clear seas.
9. The Bay of Kotor, Montenegro
A dramatic, fjord-like bay hemmed in by mountains, with the walled town of Kotor at its inner end. The region is a UNESCO World Heritage Site. Climb the walls early before it gets hot, then base yourself in a quieter bay village such as Perast for swimming.
Best for: dramatic scenery in a compact area.
10. The Amalfi Coast, Italy
Cliffside towns, lemon groves and boat trips to coves you can’t reach by road. Book ahead, as it’s popular in summer, and base yourself in one town to avoid the busy coast road. Use our guides to Positano over a weekend and the Amalfi Coast.
Best for: a classic Mediterranean escape.
11. San Sebastián and the Basque coast, Spain
Northern Spain stays milder than the south in summer. San Sebastián has a beautiful town beach, La Concha, and an old town known for pintxos, Basque bar snacks. Add a day trip along the coast to fishing villages or inland to Rioja’s vineyards.
Best for: food lovers who want a beach.
12. Naxos, Greece
The largest of the Cyclades has long sandy beaches, mountain villages and a strong local food culture. It’s often calmer than Mykonos and Santorini nearby. Ferries connect it with Piraeus near Athens. See the best places to visit in Greece for more islands.
Best for: beaches and food at a slower pace.
How to choose
- If you want to escape the heat: go north or up. Copenhagen, the Wadden coast, Luxembourg and the Alpine lakes stay comfortable when the Mediterranean hits its hottest.
- If you want warm sea swimming: Croatia, Montenegro, the Amalfi Coast and the Greek islands are at their best from June to September.
- If you don’t want to drive: Lucerne, Copenhagen and Berlin work well by public transport.
- If you want fewer crowds: go in June or September, or pick the quieter base near a famous spot, such as Perast instead of Kotor.
Tip: In southern Europe, plan sightseeing for the morning and evening. Spend the hottest hours in the shade, in the water or over a long lunch.
