Brunnsviksbadet is a public swimming beach at Brunnsviken in Frescati Hage, within the Ekoparken park. The city describes it as child-friendly. There are rocky areas and small grassy patches, plus a fixed platform leading to two floating piers with swimming ladders and a bathing raft. In summer, buoy lines mark the bathing area, and the city puts out a temporary toilet. There is no dedicated changing room, shower, kiosk or food service.

Park paths lead to the beach from Frescati Hagväg and Lilla Frescativägen. Visit Stockholm suggests walking or taking the subway to Universitetet station. The beach is also within 500 metres of the metro and Roslagsbanan railway, according to the city. There is no car parking beside the beach.

The city says dogs are prohibited at the beach from 1 June to 31 August, except guide and assistance dogs. Lifesaving equipment is provided. The city does not give an admission price in its listing. Its information describes summer facilities and does not give year-round operating dates, so it does not establish whether swimming facilities are available this week.
