• No lifeguards on duty at the beach, so keep swimmers within reach; the city posts water quality and temperature on ulkoliikunta.fi in summer
• Boat from Merisatama (Merisatamanranta 8) from mid-April to mid-November, and a walking pontoon bridge from the mainland the rest of the year
• Bring your own firewood for the fire pit by the beach; fires are banned whenever a wildfire warning is in effect

Uunisaari is a small island just off Kaivopuisto, made of two islets joined by a wooden bridge. Its sandy-bottomed public beach has a playground, changing room, toilets and showers, with a fire pit and picnic table nearby.

Sand roads loop the island, and a walking path leads across to neighboring Liuskasaari. A restaurant, a seasonal café and two seaside saunas sit by the shore.
