Tenerife: Siam Park vs Whale Watching (2026 Comparison)

Quick verdict: Whale watching is the better value day (from €28, rated 4.7 from 17,965 reviews) and Tenerife has resident pilot whales year round, so sightings do not depend on season. Siam Park from €44 is the full-day option; its all-inclusive version at €165 costs €121 more and only makes sense for a group that will eat and drink all day.

These are the two biggest paid days out on the island, and one costs nearly six times the other. Here is what each buys.

Prices and ratings are live GetYourGuide figures checked in August 2026. Most options include free cancellation up to 24 hours before.

This is the real decision on Siam Park, and the numbers are stark. Standard entry is €44, rated 4.5 from 17,629 reviews. The all-inclusive version is €165, a difference of €121 per person.

It rates higher at 4.7, but from only 1,194 reviews against 17,629, so that rating rests on a much smaller sample. The upgrade pays off for a family that will eat two meals and drink in the park all day. For a couple planning to bring a packed lunch, it does not come close.

The water between Tenerife and La Gomera holds resident populations of pilot whales and bottlenose dolphins, present all year rather than migrating through. That is unusual, and it is why sightings here are more reliable than at most whale watching destinations.

At €28 it is the cheapest of the three bookings and rated 4.7 from 17,965 reviews, almost exactly as many as Siam Park's standard ticket. Trips are typically a half day, so unlike the park it leaves the rest of your day free.

They are not really alternatives if you have a week: the whale trip is a half day and the park is a full one. The sensible order is whale watching early in the trip, when a rough-sea cancellation still leaves room to rebook, and Siam Park on a settled hot day.
