Outdoor Pool of Marignac – Grand-Lancy

An outdoor swimming oasis just steps from Geneva

Nestled in the heart of Grand-Lancy, the Piscine de Marignac is one of the large outdoor swimming pools in the canton of Geneva. On a classified and wooded site, you will find a huge Olympic pool, a non-swimmers' pool, a paddling pool for the little ones, and large lawns to lay your towel. Everything you need to spend an entire day without getting bored, from the first splashes to the big dive.

What your children will discover

The site features several pools designed for every age and every desire. The youngest can splash safely in the shallow paddling pool, while the older kids can try out the slides, water games, and, for the experienced swimmers, the diving boards (from 1 m up to the famous 10 m platform). The large 50 m Olympic pool also allows for serious swimming, and the beach volleyball courts and play area provide opportunities to move between swims.

What to do there and the atmosphere on site

Marignac embodies the spirit of a "day at the pool" in all its simplicity: you arrive with your beach bag, settle on the lawn, and alternate between swimming, snacks, and naps in the shade. The atmosphere is family-friendly and relaxed during the week, more lively on beautiful summer days. A restaurant and a kiosk on site provide drinks or snacks without having to pack up. It’s a place where you can easily spend several hours, even the whole day.

Before you go

• Recommended age: from 3 years old thanks to the paddling pool and water games; the pools and diving boards will also delight older kids and teens.
• Duration: plan for half a day, or even a full day when the weather is nice.

• Reservation: there is an online ticketing system; check the terms and any available slots on the official website before coming.

• Accessibility for people with reduced mobility: a water lift facilitates access for people with reduced mobility.

Parents' tips

• Arrive early on hot days to find a shady spot on the lawn.
• Locate the paddling pool upon arrival and set a meeting point with the older kids.

• Consider armbands for children who cannot swim yet.
