Pool day passes in Cascais start at €15 for a saltwater ocean pool on the Guincho coast and go up to €75 for a luxury resort brunch with pool access. Three venues sell day passes to non-guests, covering outdoor ocean pools, resort pools, and indoor spa facilities.
Ocean pools and beach clubs
Arriba by the Sea sits right on the Guincho coastline, about 10 minutes from Cascais centre. Their massive saltwater pool is fed by the Atlantic, so it's cold but striking. Entry costs €15 on weekdays and €20 on weekends, with sunbeds and umbrellas rented separately. It's a favourite with locals and families, and the views of the Atlantic waves are hard to beat.
Resort and spa pools
The Sheraton Cascais Resort in Quinta da Marinha runs summer packages that combine dining with pool access. Their Sunday Pool Brunch includes a full buffet, live entertainment, and afternoon pool use for €75. On weekdays, the Sip & Soak deal gets you a light lunch and pool access from 1 PM to 7 PM at the same price.
For a wellness focus, The Oitavos offers access to their indoor seawater jet pool, sauna, and Turkish bath for €30. It's a good option on cooler or windy days when the outdoor pools aren't appealing.
How Cascais compares
Cascais is a 30-minute train ride from Lisbon, making it easy to combine both in a trip. Prices here are lower than Lisbon's rooftop pool scene, where day passes run €25 to €95. For larger resort pools with warmer water, the Algarve has all-inclusive options from €40. Porto offers a similar mix of spa pools and architectural saltwater pools further north.

BookFrequently Asked Questions
Pool Day Pass FAQs for Cascais
Yes. Pools like Arriba by the Sea are fed directly by the Atlantic, so water temperatures typically sit around 17°C to 20°C (63°F to 68°F) even in summer. Refreshing but brisk.
For weekends in July and August, yes. It's a large venue though, so arriving before 11 AM on weekdays usually gets you a spot without a reservation.
Not at outdoor saltwater pools like Arriba. For indoor hotel spas like The Oitavos or the Sheraton's wellness facilities, swim caps are mandatory. Pack one just in case.
