A Secret Autumn Treasure – The Hidden Gems of Helsinki’s Archipelago

Aug 22, 2025

Autumn arrives in Helsinki gently: colorful leaves start to fall on the streets, and the sea turns a deep shade of blue. Many think of Helsinki as a maritime summer city, but did you know that autumn is one of the best times to experience the archipelago? When the boating bustle of summer calms down and the air grows crisp, the autumn colors paint the shores, opening up space and a whole new sense of tranquility at sea. And if you look a little further, beyond the city skyline, you’ll find a world many people pass by in their daily rush. Helsinki’s archipelago is full of places – hidden gems that often go unnoticed, even though they are only a short boat ride away.

When the city fades behind you

A cruise in Helsinki is not just a summer pastime for tourists. Step aboard a Royal Line vessel from the Market Square. As soon as the ropes are untied, the city’s sounds fade away. Ahead of you lies a view of the archipelago, holding stories, history, and peaceful nature. In autumn, the islands are wrapped in atmospheric light, and the scenery looks entirely different from summer. Even a short trip by sea offers a fresh perspective on familiar places. Each island has its own character – and with the ever-changing weather, autumn brings a very special atmosphere.

Four stories from the archipelago

  • Vallisaari – once a bustling military island, now a haven of peace. A fusion of nature and history, glowing with autumn colors. In Vallisaari, it’s easy to forget that the city center is just fifteen minutes away.

  • Lonna – a tiny island next to Suomenlinna. Once known as a base for minesweepers, today it offers a warm cup of coffee and a view where the sea and city meet in perfect harmony.

  • Pihlajasaari – a popular swimming spot in summer, but nearly deserted in autumn. The silence and sea air make it a uniquely wonderful place for a deep breath and a small escape from everyday life.

  • Views of Katajanokka and Kruunuvuorenselkä – not an island as such, but from the sea, the autumn cityscape with its church spires and lights is an experience even many locals have never seen.

As the air turns crisp, you can enjoy your journey in the warmth of the ship’s interior, perhaps over lunch, or dress warmly according to the weather and soak in the atmosphere on deck. From the ship’s café, you can get a hot drink and a light snack to crown your trip.

Find your own maritime moment

Royal Line makes the archipelago easily accessible even in autumn. You don’t need a travel plan for the cruise – just let the sea guide you. Whether you’re a visitor or a local, Helsinki’s archipelago offers an emotional experience and reminds you how unique our capital’s marine nature truly is.

See you on board!
