Siam Park: What to Know Before You Go

Siam Park is a Thai-themed water park in Costa Adeje, on Tenerife's south coast, and the largest water park in Europe by area. It's owned by the Loro Parque Group — the same company behind Loro Parque in Puerto de la Cruz and Poema del Mar in Gran Canaria — and draws well over a million visitors a year, regularly topping international rider-voted rankings (including repeated TripAdvisor Travellers' Choice wins) as one of the best water parks anywhere.

The whole park is built around a consistent Thai theme — carved architecture, planting, and staff uniforms — rather than treating it as decoration bolted onto a standard water park layout, which is part of why it photographs and feels so different from a typical resort pool complex.

The park opened in 2008 and covers roughly 18.5 hectares (about 46 acres), which is part of why a single visit genuinely justifies a full day rather than a half-day stop — walking between zones takes real time on its own, before factoring in queues or time spent relaxing. The shark tunnel inside Tower of Power isn't a gimmick tacked onto the ride: it's a proper aquarium section housing several species of shark and ray, visible to riders for only a few seconds but maintained as a genuine marine exhibit behind the scenes, in keeping with the wider Loro Parque Group's focus on animal husbandry and conservation across its attractions.

Beyond the individual rides, Siam Beach is a wave pool that holds a Guinness World Record for the largest artificial wave at a water park, with white imported sand and a genuinely beach-like feel rather than a standard swimming-pool edge. The Lost City is a separate, gentler zone built specifically for smaller children, with scaled-down slides and shallow pools well away from the main thrill-ride traffic.

General admission runs roughly €38–€47 for adults and €26–€34 for children aged 3–11 depending on the season and how far ahead you book, with under-3s admitted free; Canary Islands residents get a substantial discount (commonly cited around 40–50% off) with valid local ID. Because Siam Park adjusts pricing seasonally and periodically runs promotions, treat these as a planning range rather than an exact figure, and check the official Siam Park website for the current price on your specific date before booking.

The park is generally open daily year-round (with limited exceptions such as Christmas Day), typically 10am–6pm from March to October and 10am–5pm from November to February. During July and August, "Siam Night" runs on selected evenings (commonly Tuesday to Saturday), transforming the park after dark with lighting, live DJs and a more adult, festival-like atmosphere on a separate ticket — worth considering as an alternative to a standard daytime visit if you're travelling without young children in peak summer.

• ✓A free shuttle bus runs from many south-coast hotels; check with your hotel reception or the official website for the current pickup schedule, as it can change seasonally.
• ✓Driving yourself is straightforward from anywhere in the south — the park has its own paid car park, typically a modest daily fee.
• ✓Book online in advance rather than buying at the gate: it's usually cheaper, guarantees entry on days with capacity limits, and avoids a genuinely long ticket-office queue in peak season.
• ✓Arrive at opening time if you want to ride Tower of Power and the other headline slides without a long wait — queues build steadily through the late morning.
• ✓Fast-track add-ons exist for most rides but typically exclude Tower of Power and the Mai Thai River lazy river — worth knowing before assuming a Fast Pass covers everything.
• ✓Food and drink are available inside from several restaurants and snack bars, though many visitors find it cheaper to eat a proper breakfast beforehand and treat park food as a top-up rather than a full meal plan.

Lockers are available throughout the park and are worth renting for the day rather than trying to carry a bag between rides — most visitors find one central locker near the entrance simpler than several smaller ones scattered around. Sun loungers and parasols can be rented, and given how much of a day here is spent moving between direct sun and water, reef-safe sunscreen reapplied through the day matters more than it might at a standard beach visit, since the constant water exposure washes ordinary sunscreen off faster than sitting on sand does.

Swimwear with metal fastenings, buckles or exposed zips is generally not permitted on the faster slides for safety reasons, so a simple swimsuit or trunks without hardware is the safest choice. Water shoes aren't required underfoot inside the park itself, but many visitors bring a pair for the walk between the car park and the entrance, or if they plan to visit a rockier beach the same trip.

Because Costa Adeje's climate is reliably warm and dry for most of the year (see our full weather and climate guide), Siam Park doesn't really have an "off season" in terms of conditions — the more useful variable to plan around is crowd levels rather than weather. July, August, and the Christmas and Easter school-holiday windows bring the heaviest crowds and the longest queues on headline rides; visiting in the shoulder months (May, June, September, October) typically means a noticeably calmer park at close to the same weather.

Within a single day, arriving right at opening and heading straight for Tower of Power, Vulcano and Singha before mid-morning is the most consistently repeated piece of advice from regular visitors — queues on these three rides build fastest and stay long through the middle of the day, easing off again in the last couple of hours before closing.

Siam Park skews more thrill-oriented than some rival water parks — a meaningful share of its signature rides carry a 1.25m+ height requirement, and Tower of Power specifically requires both a 1.40m minimum height and a minimum age of 14. Families with younger children are well catered for through The Lost City and the several 1.10m-minimum family raft rides, but if your group is mostly under 8, it's worth measuring children in advance and setting expectations that some of the park's most famous attractions simply won't be accessible yet.

For teenagers, groups of adults, and couples, this thrill-heavy lineup is exactly the draw, and it's part of why Siam Park differs meaningfully from more family-uniform water parks elsewhere on the island or in mainland Spain.
