What's Inside (Aquarium + Planetarium)

Planet Ocean is really two attractions under one roof, and a single ticket covers both. The aquarium recreates nine aquatic environments, leading you from cold polar waters through Mediterranean reefs to a steamy tropical forest. The centrepiece is one of France's largest indoor tanks — an 18-metre-wide, 10-metre-tall basin where sharks, rays, and shoals of pelagic fish circle overhead. Across the full circuit you will meet penguins, sea turtles, jellyfish, and clownfish among the 3,500-plus animals.

The planetarium, housed in a tilted dome, runs rotating immersive shows projected across the full ceiling — astronomy programmes for adults and gentler space adventures aimed at younger children. Shows are scheduled throughout the day, so check the screening times when you arrive and slot one between aquarium loops. Most families spend around two hours on site, longer if you catch a planetarium show. It is a reliable rainy-day or midsummer-heat option, and pairs well with a half-day at the neighbouring Parc Zoologique de Lunaret for an animal-themed weekend. Travelling with little ones?

Tickets & Prices

Planet Ocean is a paid attraction — there is no free general admission. As of 2026, standard on-site prices are:

• Adult (13+): €19.50
• Child (5–12): €14.00
• Child (3–4): €6.50
• Under 3: free

Family packages and reduced rates for groups are also offered. Buying online in advance is worth it: e-tickets are typically a touch cheaper than the gate and route you into a dedicated fast-track queue, which matters on busy weekends and during school holidays. Tickets are valid for both the aquarium and the planetarium, so there is no need to choose between them. Always confirm the latest pricing on the official site at planetoceanworld.fr before you go.

Opening Hours

Planet Ocean Montpellier is open every day of the week, with seasonal hours:

• April to August (and spring/summer school holidays): 10:00–19:00, last admission 17:30.
• September to March: 10:00–18:00, last admission 17:00.

Because the last entry is set roughly an hour before closing, aim to arrive by mid-afternoon at the latest to enjoy both the aquarium circuit and a planetarium show without rushing. Hours can shift slightly around public holidays, so double-check the official calendar when planning a 2026 visit.

Getting There (Tram Line 1 to Odysseum)

Planet Ocean sits at Allée Ulysse, Odysseum, 34000 Montpellier, in the Odysseum commercial and leisure district east of the city centre. The easiest car-free route is Tramway Line 1 (blue line): ride it to its eastern terminus, the Odysseum stop at Place de France, then it is a short, signposted walk to the aquarium entrance. Line 1 runs directly from Montpellier Saint-Roch railway station and the historic centre, so you can arrive in the city by train and reach Planet Ocean without ever needing a car.

Drivers will find ample paid parking across the Odysseum complex. The area also has cinemas, restaurants, and an ice rink, making it easy to build a full day around your visit. For more car-free ideas and onward routes, browse the rest of our things to do in Montpellier guide.
