Lake Malta is situated just to the east of the city centre, and Rondo Śródka - at the lake's northwest corner, is the best place to access it. Below are the public transport options from three main points in the centre. Alternatively, a taxi from the centre to the north shore will cost about 30-35zł.
From the main train station: Take tram number 6 from the 'Poznań Główny' stop (walk just past the Avenida shopping centre going east) directly to 'Baraniaka'. The journey takes about 14 minutes.
From the Old Town Square: Take tram number 3, 4, or 17 from either 'Pl. Wielkopolski' or 'Małe Garbary' to 'Rondo Śródka'.
