Day 1: The Best of Stockholm in 24 Hours
Gamla Stan — Medieval Old Town
Start in Gamla Stan — Stockholm's medieval island centre with cobblestone lanes dating to the 13th century. Walk Västerlånggatan and the narrowest alley, Mårten Trotzigs Gränd (90cm wide). Visit the Royal Palace (180 SEK) for the lavish State Apartments, or just admire the exterior and watch the changing of the guard at 12:15pm. Stortorget — the colourful main square — is the heart of Gamla Stan. Coffee at Chokladkoppen on the square.
Vasa Museum & Djurgården
Ferry or walk to Djurgården island for the Vasa Museum (190 SEK) — a fully intact 17th-century warship that sank 20 minutes into its maiden voyage in 1628. The ship is 95% original timber, 69 metres long, and covered in 700 carved sculptures. It's the world's best-preserved warship and Stockholm's most visited museum. Grab lunch at Rosendals Trädgård — an organic garden cafe in a greenhouse (sandwiches 85–110 SEK).
Södermalm — Hipster Island
Head to Södermalm — Stockholm's coolest island, home to vintage shops, craft beer bars, and the characters from "The Girl with the Dragon Tattoo." Walk to Monteliusvägen for the best sunset viewpoint in Stockholm — a clifftop path overlooking Gamla Stan, City Hall, and the water. Dinner at Kalf & Hansen on Mariatorget (Swedish comfort food, mains 145–195 SEK) or Meatballs for the People (yes, it exists, 155 SEK).
