Siam Park (Costa Adeje)

Consistently voted the #1 water park in the world by TripAdvisor Travelers' Choice (since 2014), Siam Park is a Thai-themed water kingdom spread across 18.5 hectares in Costa Adeje. The park features 15 major attractions set within lush tropical gardens with authentic Thai architecture, including temples, floating markets, and a sea lion colony. Signature rides: Tower of Power (a near-vertical 28-meter drop slide that passes through an aquarium of sharks and rays), Singha (a high-speed racing water coaster with uphill jets), The Dragon (giant funnel ride), and the Wave Palace (generating the world's largest artificial waves up to 3 meters high in a beach-entry pool). For younger children, The Lost City is a dedicated splash-and-climb zone with mini slides, water cannons, climbing frames, and shallow pools. The Mai Thai River (lazy river) winds through the entire park. Facilities include free sunbeds, lockers (€5 deposit), restaurants, and a swim-up cocktail bar. The park operates its own free bus from major resorts in south Tenerife (Playa de las Américas, Los Cristianos, Costa Adeje). Open daily 10 AM–6 PM (summer until 7 PM). Tickets: €40 adults, €28 children (3–11), free under 3. Fast Pass available (€18). Combo tickets with Loro Parque available. Parking: €4. Highly recommended: arrive at opening time for best access to the most popular slides before queues build.
