A tiny island off Kaivopuisto with a sheltered swimming beach, a cafe terrace and two saunas that can be booked privately. Summer boats run from Merisatama (Aava Lines, April to November per the city); in winter a floating pontoon footbridge from Kaivopuisto replaces the boat.
Uunisaari Island Beach is a small, sheltered swimming spot on a tiny island just off the Kaivopuisto district of Helsinki, in the Uusimaa region of Finland. The address given is a boat departure from Merisatamanranta 8, and the island lies about 3 km south of the city centre. The beach is compact rather than expansive, set in a protected inlet where the water is calm, shallow near the shore and typically clear and brackish. It is a cove-style bathing place rather than an open strand, so waves are minimal and conditions suit gentle swimming. The island has a relaxed, slightly boutique character, with a cafe terrace, a small sunny lawn and two saunas that can be booked privately, which fits the Finnish habit of alternating heat and cold water. The atmosphere is quieter and more adult-oriented than the big city beaches, though families do visit. Amenities include a cafe with a sun terrace that opens in early June, and a service building with toilets and showers that the city page lists as staffed from 8:00 to 16:00. The saunas should be reserved in advance through the operator. Access is by waterbus from Merisatamanranta 8, operated by Aava Lines from April to November according to the city, and the crossing is under five minutes. From about November to April, a floating pontoon footbridge from the end of Kaivopuisto park replaces the boat, although the dates vary and should be confirmed on hel.fi. The island is therefore reachable on foot in winter, when it becomes popular with people combining ice swimming and sauna. Kaivopuisto itself offers walking paths, embassies and sea views, making it easy to pair the island with a stroll before or after a swim. Because the beach is small, space can run short on warm summer afternoons, so arriving earlier in the day or on a weekday is sensible. Cafe prices and sauna fees should be checked locally.
