2025-06-27

1. Number one favourite: Pihlajasaari island

Pihlajasaari island (commonly known as Pihlis) is a former villa island which has been a summer paradise for helsinkians since 1930s. Beautiful nature, sandy and rocky beaches, versatile recreational areas and amazing views are the main attractions of the island. There are still some of the old villas at the island and in one them you’ll find summer restaurant Pihlajasaari. Have a nice walk through the woods and groves, and enjoy the sea breeze when standing at the cliffs. You can rent a sauna by the sea or camp overnight at the camping area. Also, one of the few naturist beaches of Helsinki can be found on the eastern part of the island.

Waterbuses operate from Merisatama and Ruoholahti to Pihlajasaari. The trip takes approx. 20 minutes. You’ll get near Merisatama by the Hop On-Hop Off bus (get off at stop 6) trams 1 and 3 or busses 20 and 30 from Kamppi. You’ll get to Ruoholahti by metro or tram 8. Remember, with Helsinki Card you travel for free in busses, trams and metros!

2. A gem next to Kaivopuisto: Uunisaari island

This tiny Uunisaari island just next to Kaivopuisto park is like a hidden gem with a nice beach and an interesting history. In the summertime you can reach the island by a small waterbus, the trip takes less than 5 minutes. During autumn and winter, you can walk straight to the island via a pontoon bridge. The history of the Uunisaari is versatile as the island has hosted an oil boilery and a paint factory, just to name a few. At the end of the 1800s Uunisaari was famous for its seaside spa and in the 1930s swimming facilities. There are only ruins of those now, but the island does have a very nice and sandy beach. The most daring ones dip into the sea straight from the cliffs and rocks. You can enjoy a lunch or a coffee at restaurant Uunisaari or shop for refreshments at a small kiosk. Also check out their sauna facilities. Uunisaari linked to the neighbouring Liuskasaari island by a breakwater.

There’s a non-stop waterbus connection to Uunisaari during summer months. The waterbus leaves from Merisatamantori (Neitsytpolku 1). Closest Hop On Hop Off stop: 5.

3. Suomenlinna – A UNESCO World Heritage Sea Fortress

Just a 15-minute ferry ride from the Market Square, Suomenlinna is one of Helsinki’s most iconic islands and a must-visit destination. This historic sea fortress, spread across several interconnected islands, offers a unique blend of culture, nature, and history. Stroll along cobblestone paths, explore fascinating museums, or enjoy a peaceful picnic by the sea. Suomenlinna is ideal for a relaxed day trip and is open year-round.

Public HSL ferries (free with the Helsinki Card) and private waterbuses during the summer months (discounted with the Helsinki Card) have frequent daily departures from the Market Square.

4. Trendy island destination: Island of Lonna

After opening for public 2014, the small Lonna island soon became one of the trendiest recreational island of Helsinki. Join this cool and relaxed atmosphere, enjoy some organic and local food at a restaurant or purchase your own picnic basket with lots of delicacies. You can also take some sauna time and dip into the sea! At Lonna island you’ll find both men’s and women’s loft saunas. Saunas are heated up with wood burning stoves and you can buy a 2-hour pass which allows plenty of time to relax and enjoy both the heat and the scenery.

You can stop by at Lonna with an island hopping ticket or head to the island with a private waterbus leaving from the Market Square. The trip takes about 10 minutes.
