Siam Park in Costa Adeje has held the TripAdvisor title of World's Best Water Park more times than any other venue on the planet. That is not a marketing claim — it is the result of hundreds of thousands of independent visitor reviews. And having visited, most people agree that it deserves the title. But knowing how to navigate it well makes the difference between a great day and a very long, hot queue.
The park is built around a Thai architectural theme that is unusually elaborate for a water park — ornate temple facades, carved stone features, and lush tropical landscaping throughout. It does not feel like a generic waterpark. The theming adds a genuine sense of place, and the scale of the main beach pool (with its real wave-generating machine) is genuinely impressive. When the waves start, it takes a moment to process that you are not at the ocean.
The must-do rides: the Tower of Power is the signature experience — a near-vertical drop through a transparent tube submerged in a shark tank, reaching speeds of up to 80km/h. It sounds terrifying and is. The Dragon is a slower but highly physical experience — a multi-person raft that banks sharply around tight curves before a final plunge. The Volcano is the park's classic multi-lane speed slide, reliable for direct comparisons between friends. For younger visitors, the Jungle Snakes zone has family-friendly slides that maintain genuine thrills without the extreme drop factor.
Queue strategy is critical. The Tower of Power and Dragon consistently build the longest queues as the day progresses. The optimal strategy is to arrive when the park opens at 10am and head directly to one of these two first. By noon, queues for both can exceed 45 minutes. After 3pm, queues shorten significantly as families with young children begin to leave. If you arrive late, use the afternoon for the popular slides and the morning for the beach pool and lazy river.
What to bring: the basics are sunscreen (very high factor — you are in the water and sun for hours), water shoes for the hot paving between attractions, a secure waterproof bag for phones and valuables, and cash or card for food and drinks inside. The lockers at the park entrance are reasonably priced and worth using for anything you do not want to carry. Towels can be rented on-site but bringing your own saves the cost and queue.
The food at Siam Park is significantly better than standard waterpark fare. The restaurants serve Thai-influenced dishes alongside burgers and sandwiches, and the quality is above what you would expect. The beach bar is a pleasant spot for a break. Bringing outside food is not permitted, but the in-park options are sufficient for a full day. Budget around €15-25 per person for food and drinks inside.
The VIP package deserves a mention for groups who want to avoid queues entirely. VIP guests get priority access to all rides, a dedicated beach area, and a food and drinks allowance. The cost is significantly higher than standard admission but can be worth it for groups visiting in peak summer when standard queues are longest.
Nearby, Loro Parque in Puerto de la Cruz offers a combined ticket with Siam Park that provides good value if you plan to visit both. The two parks are about an hour apart by road, so most visitors choose to split them across two separate days rather than attempting both in one. Siam Park is in Costa Adeje, a 10-minute taxi from Playa Las Americas — entirely accessible without a hire car.
One honest note: Siam Park is extremely busy in July and August and during Spanish school holidays. If your travel dates are flexible, May, June, September and October offer the best combination of good weather, open rides, and manageable queues. A weekday visit is always preferable to a weekend. Whatever day you go — arrive at opening time.
