• Half-day tickets cover 9:30am to 2:30pm or 2:30pm to 7pm, handy for a morning-only swim
• Family ticket covers up to 2 adults plus kids under 16, and you need proof you're related
• Diving boards can close when lifeguards shut one or more platforms for safety, so don't promise the top board

Two pools filled from the sea sit side by side at Oeiras Marina, next to Praia da Torre and looking out over the mouth of the Tagus.

Small kids get a 330 m² pool only 40cm deep; older swimmers get a big main pool and a diving tower with boards up to 7.5 meters. Lawns, loungers, umbrellas, a restaurant-bar, changing rooms and lockers surround the water, with lifeguards on duty.
