To purchase a "Fast Pass" for Siam Park in Tenerife in 2026, you can either buy it online in advance via the official website or at the ticket office upon arrival. There are several tiers: the "Fast Pass Unlimited" allows priority access to almost all major slides (excluding the Tower of Power and the Mai Thai River) and is often sold as a "wristband" for the day. For those seeking the ultimate luxury, the "All-Inclusive" or "VIP" tickets come with the Fast Pass already included in the price, along with food, drinks, and a locker. Because Siam Park is consistently ranked as the #1 water park in the world, the Fast Pass is highly sought after; on peak summer days, the in-park allocation can sell out within the first hour of opening. It is also important to note that the Fast Pass is "date-specific" and non-transferable. If you haven't pre-booked, your best strategy is to arrive at the park at least 30 minutes before opening and head straight to the "Floating Market" or the main entrance kiosks, as these are the primary locations where the daily wristbands are distributed until they reach their strict capacity limit.
