Hagaparken is what happens when an 18th-century king reads about English gardens and has the money to build one. Gustav III laid it out along Brunnsviken in the 1780s — lawns instead of parterres, a pavilion, a temple, a set of painted copper tents that exist mostly to look like a fantasy — and it remains the loveliest place within a short bus ride of the centre.
Take the 515 from Odenplan and start at the Koppartälten, the copper tents, where there's a café before you set off. From there the park unfolds along the water: Gustav III's Pavilion above the shore with its remarkable neoclassical rooms; the Ekotemplet on its rise, built so a voice carries across it; and the long Haga lawns running down to the bay — the first English-style landscape garden in Sweden, and still the best place in the city to lie on grass.
If the weather turns, the Fjärilshuset — a glasshouse of loose tropical butterflies — is the warm fallback. Otherwise stay outside, follow the Brunnsviken shore back to the bus, and let the city stay out of sight a while longer.
