• Off-season visits are free, but most snack bars and rentals run on limited service outside June to August
• Lifeguards on selected beaches during the summer paid-entry hours, so pick one of those with younger swimmers
• Shade under the trees on the South side; elsewhere bring a parasol or rent one on the beach

Sun Lakes (Slnečné jazerá) is a lakeside resort split into three zones around the water, with beaches that slope gently into the lake and playgrounds on shore.

Kids can rent pedal boats, paddleboards and kayaks, bounce on inflatable castles, or play minigolf, tennis and beach football in the South zone. The East zone adds a water trampoline, and snack bars and langoš stands line the shore.
