Siam Park

Siam Park opens 365 days a year on Tenerife's south coast, in Costa Adeje, inside the municipality of Adeje. Those two facts, an all-year schedule and a location in the island's driest and sunniest corner, explain most of why the park dominates water-park planning for Tenerife visitors. The rest of this page works through what the verified sources actually say: the seasonal opening hours from the park's own site, the award record attributed the only way it can honestly be attributed, and the AEMET climate normals that tell you which months give you the warmest water and the fewest rain days. Where a question has no verified answer, this desk says so rather than guessing. The practical pages that frame a visit, including the wider water park guide for Tenerife, carry the comparisons; this one stays on Siam Park itself.

Why Is Siam Park So Popular?

Siam Park is popular for reasons the sources support rather than slogans: it opens 365 days a year in Costa Adeje, on the dry south coast of Tenerife where AEMET's airport station records zero days of rain of one millimetre or more in June and July, and its operator's release records a Travellers' Choice award from Tripadvisor for best water park in the world for a fifth consecutive year.

The award line needs care, because most pages online state it loosely. Loro Parque's own release says: "For the fifth consecutive year, TripAdvisor has awarded them the Travellers' Choice Award for the Best Waterpark in the World." That is the supportable wording, attributed to the operator's release. Later years were not confirmed on the awarding body's page, so this desk does not extend the claim beyond what the release says. An undated release, an attributed quote, and no more.

Climate does the other half of the work. The park is a water park in a place where the sea off the south coast averages 23.7 degrees Celsius in September and October per NOAA's 1991 to 2020 figures, and where the air at the nearby airport station averages a mean daily maximum of 28.4 degrees in August. A water park that never closes, in a resort belt built for winter sun, is almost guaranteed a steady stream of visitors: 7,412,046 tourists arrived in Tenerife by air in 2025, and the south absorbs the bulk of the resort demand. For the full picture of what else fills a week, the things to do in Tenerife page is the round-up.

What Are the Siam Park Opening Hours?

Siam Park opens every single day of the year. From 1 May to 29 Oct it runs 10:00 to 18:00, and from 30 Oct to 30 Apr it runs 10:00 to 17:00, per the park's own opening-hours page. There is no closing day, no winter shutdown and no weekday reduction in those figures.

The seasonal split matters for planning more than it looks. The summer window gives you an extra hour each evening, which in practice means the last hour is often the calmest, as day-trippers thin out and the queues shorten. The winter window closes at 17:00, so a December visit needs the morning: arrive at opening, do the headline slides first, and let the afternoon absorb the slower attractions.

Two practical notes follow from the sources. First, hours are the park's own published figures and can be suspended for weather alerts, the same way Tenerife ON suspends trail bookings for fire risk and weather on Teide; the park's site is the place to check on the morning. Second, ticket prices are not printed here because none was confirmed on an official page: the live listing carries the current price, and the product card below shows it.

Where Is Siam Park and When Is the Best Time to Visit?

Siam Park is in Costa Adeje, in the municipality of Adeje, on Tenerife's south-west-facing tourist coast. The best visiting window by the numbers is May to October: AEMET's Tenerife South Airport station records one millimetre of rain or more on 0.2 days in June, zero in July and 0.2 in August, and the sea off the south coast averages 21.4 to 23.7 degrees Celsius from June to October.

The location matters for logistics. Costa Adeje is the heart of the south resort belt, within the same municipality as the grey-sand Playa del Duque beach, which the tourist board describes in exactly those words. Everything in this corner, the beaches, the park and the harbours at Puerto Colon and Los Cristianos, sits close enough together that a morning in the water park and an afternoon on a boat are realistic on the same day.

The climate table below is AEMET's 1981 to 2010 normals for the station at Tenerife South Airport, 64 metres above sea level, a few kilometres from the park. It is the closest long-run record to Costa Adeje that the official network publishes.

Two readings follow. The rain column is the one to trust for planning: even the wettest month, December at 30 mm, is drier than a single grey week in northern Europe, and the rain-day count stays under four all year. The sunshine column is the one that explains the park's year-round viability: the south never drops below 168 hours a month, which is why a January water-park day is a real proposition and not a novelty.

The sea matters too, because a water park visit often pairs with a swim stop or a boat afternoon. NOAA's 1991 to 2020 series for the sea surface off the south coast reads as follows; note the two datasets cover different periods, 1981 to 2010 for the air and 1991 to 2020 for the sea, and neither figure should be quoted with the other's period.

Crowds are the third variable. The ISTAC series for tourists arriving in Tenerife by air, excluding Canary Islands residents, shows the peaks: December 2025 brought 671,202 air arrivals and January 2026 brought 649,614, against 518,359 in May 2026. Those winter months combine high visitor numbers with the shorter 17:00 closing, so a winter visit rewards an arrival at opening time more than a summer one does.

Is Siam Park Tenerife Worth It?

For most visitors basing themselves in the south, yes: the park opens 365 days a year a short distance from the main resort areas, the climate supports a visit in any month, and the operator's release records a Tripadvisor Travellers' Choice award for best water park in the world for five consecutive years. The honest caveat is that this desk has no verified figure for ticket prices, queue times or ride-by-ride details, so the worth calculation beyond those facts is yours.

The decision usually comes down to party composition. Families with children get the most obvious value: a full day, an all-year schedule and a beach-adjacent location mean the park can anchor a day without a long transfer. Adults travelling without children get a different proposition, a morning of slides followed by an afternoon elsewhere, which is where the pairing logic of the south coast helps: the whale watching cruises from Costa Adeje leave from harbours minutes away, and the regulated waters of the Canary decree, no approach within 60 metres and authorised boats flying the Barco Azul flag, make that afternoon a calm one.

The counter-case is real and worth stating. If your holiday is short, or if your base is Puerto de la Cruz or Santa Cruz rather than the south, a full water-park day eats time that the north's attractions compete for: the dragon tree at Icod de los Vinos, the UNESCO-listed uplands of Anaga Rural Park and the volcanic landscapes of Teide National Park all make rival claims on the same hours. A family splitting a week between the two halves of the island often solves this by putting the park on a south-coast day and saving the north for another.

Does Siam Park Tenerife Have a Lazy River?

The honest answer is that this desk's verified sources cover Siam Park's opening hours, its award record and its location, and do not include an attraction-by-attraction list from the park, so no individual ride, including a lazy river, can be confirmed or denied here. The park's own website carries the current attraction list, and that is the page to check before promising one to your party.

That may feel like an evasion, but it is the difference between a guide and a rumour mill. Ride line-ups change, attractions close for maintenance, and a page that states a lazy river, a wave pool or a specific slide from memory is exactly the kind of page that goes stale. What can be stated, because the sources hold it, is the frame around the rides: the hours above, the all-year schedule, and the fact that the park's operator also runs Loro Parque, whose own hours are 09:30 to 17:30 every day of the year with a car park at EUR 7 per day, a pairing that matters for the combined-ticket question below. More of these guides are collected on Tenerife Travel Guide.

Should You Combine Siam Park with Loro Parque?

Yes, if both are on your list, because the two parks share an owner and a combined admission product exists, listed on this site as a twin ticket rated 4.7 from 8,367 reviews. Loro Parque opens 09:30 to 17:30 every day of the year in Puerto de la Cruz, while Siam Park opens 10:00 in Costa Adeje, so the pair spans both halves of the island and rewards at least an overnight split rather than a same-day double.

The geography is the thing to plan around. Loro Parque sits in Puerto de la Cruz, the historic northern resort, and Siam Park sits in the south, and the island's roads mean the two are not a casual morning-and-afternoon pairing. The twin ticket's value is that it commits you to both without paying twice at the gate, and the passes and combined tickets guide works through when that maths favours a family and when single tickets win. The Loro Parque page covers the animal park in full.

What Else Is Near Siam Park in Costa Adeje?

Costa Adeje holds more than the water park: the tourist board describes Playa del Duque as a grey sandy beach in the same municipality, the neighbouring areas of Playa de las Americas and Los Cristianos carry the bulk of the south's boat trips and surf schools, and Aqualand Costa Adeje is the second water park of the same resort belt.

A day built around the park usually has a second half, and the options cluster. Beach time is the default: the Playa del Duque page covers the grey-sand beach the tourist board itself describes, and it is the closest headline beach to the park. Water time is the alternative, and the south's two strongest products are the whale watching fleet, which operates under Decreto 178/2000 with its 60-metre approach limit and Barco Azul flag rule, and the surf beaches of Playa de las Americas, where beginner lessons run year-round on the same climate that keeps the park open.

For a second water park day, Aqualand Costa Adeje is the comparison most families weigh, and the FAQ below takes that question head-on. For a change of pace entirely, the shopping guide for Tenerife covers the retail side of the same resort belt.

How Do the Visitor Numbers Shape Your Timing?

The ISTAC series for air arrivals shows two winter peaks, December 2025 at 671,202 and January 2026 at 649,614, a spring dip to 518,359 in May 2026, and a July 2026 figure of 600,339, which means the quietest park days in the verified data fall in May and June while the busiest combine high season with the shorter 17:00 winter closing.

The pattern is consistent enough to plan on. Late spring gives you the longest closing window relative to demand: the park runs to 18:00 from 1 May, and the air-arrival figures for May and June are the lowest of the published 2026 months. Midwinter inverts that: demand is at its annual peak and the park closes at 17:00, so every hour of the day is worth more. August is the exception within the summer, 618,578 air arrivals in 2025, combining peak heat with peak crowds.

Every figure in that table counts tourists arriving by air and excludes Canary Islands residents, per ISTAC's FRONTUR-Canarias series. It is one definition among several, and it is the definition that tracks resort demand in the south most closely.
