Two Very Different Waterfronts
Water shapes both cities, but in different ways. In Copenhagen it is an urban playground. The inner harbor is clean enough that locals dive from wooden decks at Islands Brygge in the middle of town. You can rent a small electric GoBoat and steer yourselves through the canals with a picnic, no license needed. Finish with a harborside sauna on Refshaleøen.
In Stockholm the water is wider and wilder. The city spreads over islands linked by bridges, so almost every walk ends at a quay. The view from Monteliusvägen on Södermalm at sunset, looking over City Hall and the lake, is one of the best free romantic moments in Scandinavia.
Then there is the archipelago. Within an hour or two of the center you can be on an island with no cars, one inn and a jetty for swimming. Sweden's right to roam lets you walk and picnic almost anywhere, as long as you respect private homes. Copenhagen has nothing quite like it.
Where the Food Is Better
Copenhagen wins here, though Stockholm runs it close. New Nordic cooking put Copenhagen on the global restaurant map, with several Michelin-starred dining rooms and a deep bench of excellent bistros. The influence reaches down to bakeries, food halls such as Torvehallerne and summer street food at Reffen. Smørrebrød, the open-faced rye sandwich, is the lunch to share.
Stockholm eats very well too. Fika, the coffee break with a cardamom or cinnamon bun, is a daily ritual. Östermalms Saluhall is the place to graze on smoked fish and cheese, Södermalm has the most relaxed bistro scene and the city has its own New Nordic tasting menus for an anniversary-level splurge. Meatballs with lingonberries and toast skagen are the classics.
One practical difference: in Sweden, alcohol stronger than 3.5 percent is sold only at Systembolaget stores, which close early on Saturdays and stay closed on Sundays. Buy wine for an island picnic before you leave the city. In both places, book the famous dinners weeks or months ahead.
How Many Days Each Needs
Copenhagen's center is compact, flat and easy to cover. Three or four days is the sweet spot, enough for Nyhavn, Tivoli, a canal boat, a harbor swim, a few long dinners and a train up the coast to the Louisiana Museum of Modern Art and Kronborg Castle. Many couples then add another Nordic stop.
Stockholm needs more time to show its best side. Plan three nights in the city for Gamla Stan, the Vasa Museum, Djurgården by bike and dinners in Södermalm, then one or two nights on an island such as Grinda, Sandhamn or Utö. Rushing the archipelago into a day trip misses the point, which is the slow evening on the jetty when the day-trippers have gone.
So if your honeymoon is a long weekend or one stop on a bigger European trip, Copenhagen fits more neatly. If you have five or six nights to give one place, Stockholm uses them better.
Seasons and Light
Both cities peak from June through August. Highs sit in the upper 60s to low 70s Fahrenheit, outdoor tables fill up and around midsummer the light lasts past 10 p.m. Copenhagen's Sankt Hans evening on June 23 brings bonfires along the beaches and lakes. Stockholm's Midsummer, on the weekend closest to the solstice, brings maypoles and flower crowns, though the city empties as locals head for the islands.
Timing matters more for Stockholm because of the archipelago. Ferry schedules to the outer islands are full in summer and thin to a skeleton timetable from October through March. May and September work in both cities, with lower prices and quieter streets.
For a winter honeymoon, Copenhagen has the edge. Tivoli reopens for Christmas with lights and stalls. Cafes fill with candles and mulled wine. Stockholm has Lucia on December 13 and the Christmas market in Gamla Stan, but its days are shorter and the islands are mostly asleep. Expect gray, damp weather in both.
Where Couples Stay
Copenhagen's best honeymoon base is the old center around Kongens Nytorv and Nyhavn, with grand hotels such as Hotel d'Angleterre and converted canal warehouses. Vesterbro suits couples who want cocktail bars and late dinners. Christianshavn is quieter, with canals and houseboats. There is even a hotel inside Tivoli Gardens, Nimb, with rooms overlooking the park.
Stockholm's classic splurge is the Grand Hôtel, facing the Royal Palace across the water. Smaller townhouse hotels in Östermalm feel like staying at a stylish friend's home. Skeppsholmen, a quiet museum island, makes a peaceful base. The archipelago adds a second style altogether: historic inns with simple rooms, cabins and good restaurants, such as Grinda Wärdshus, or the sailing hotel in Sandhamn's busy harbor.
In both cities, good summer hotels run several hundred dollars a night, so treat prices as approximate. Book archipelago inns well ahead for June and July, since they are small and popular with Swedes.
Getting There and Getting Around
Both capitals have nonstop service from the US East Coast, with flights of around eight hours. SAS flies to Copenhagen (CPH) from several US cities. Stockholm Arlanda (ARN) has seen nonstops from Newark and Chicago. Many couples connect through another European hub for better fares.
Copenhagen's airport sits only about 8 km from town. The M2 metro gets you to the center in about 15 minutes around the clock. Once there, bikes are king and taxis are rarely needed. Stockholm's Arlanda Express train reaches Central Station in about 20 minutes. The SL network of metro, trams, buses and some ferries uses one ticket system. Archipelago boats leave from Strömkajen and other quays.
Both cities are expensive by European standards. Copenhagen is slightly easier on the wallet day to day because you walk or bike everywhere. Stockholm's costs climb if you add island inns, though the ferries themselves are good value.
Doing Both Capitals
Combining them is easy and popular. Fast trains connect Copenhagen and Stockholm in about five hours, crossing the Øresund Bridge and the forests of southern Sweden. Short flights take a little over an hour. Fly into one and out of the other to avoid backtracking.
A relaxed eight-night plan is three nights in Copenhagen for food and canals, three in Stockholm for the old town and museums and two on an archipelago island to finish slowly. If you want something more unusual, swap the island nights for a short flight north to Swedish Lapland, where Treehotel and the Icehotel turn a city break into a city and Arctic honeymoon.
Copenhagen also makes a good hub for the Norwegian fjords. Whatever you choose, keep the total number of bases low. Two or three stops in eight to ten nights leaves time for the long evenings that make a Scandinavian summer special.
