• Fixed skating sessions, five a day with breaks between them, so arrive just before one starts rather than partway through
• Teddy-bear skating aids to rent for kids still finding their balance, charged per session like the skates
• Holiday closures: shut on Jan 1 and Jan 7, and only the first three sessions run on Dec 31 and Jan 6

An open-air ice rink at Kameni grad, on Ada Ciganlija, the Sava river island that holds the city's biggest beach. Skating runs in fixed sessions with short breaks between them.

Rental skates are on site, and small or wobbly skaters can hire a push-along skating aid shaped like a teddy bear to hold on to while they find their balance.
