What changes on 1 October
Until now you could walk up to the castle for free. From 1 October 2026, Onda's municipal tourist sights charge admission to anyone who isn't a registered resident. The Castle of the 300 Towers costs €4. The Prison Tower, Onda Natura (the Molí de la Reixa) and the Algepsar Cave cost €3 each.
There is a €10 combined ticket valid for three days, and an €8 dramatized visit that already includes admission. Strolling through the historic quarter, the squares and the streets remains free.
Prices by site
| Site | General admission | With dramatized visit |

| Prison Tower | €3 | €8 |
| Onda Natura (Molí de la Reixa) | €3 | €8 |
| Algepsar CaveTemporarily closed | €3 | Not available |
The €8 dramatized visit includes the guided activity and admission to the site.
Prices by type of visitor
| Type | Per site | Combined ticket |
|---|---|---|
| General visitor | €3 or €4 | €10 |

| School groups | €1 | €3 |

Free admission days
There are dates when you don't pay. According to the Town Council's price table, admission is free on 18 May, International Museum Day. Entry to the castle is also free during the Medieval Fair and at municipal cultural events announced in advance.
Combined ticket: when it pays off
The combined ticket costs €10 and covers all the included sights for three days in a row. If you only want the castle and one more, the separate tickets come to €7 and you're better off skipping it. With the castle, the Prison Tower and Onda Natura you're already at €10, the same as the combined ticket.
Today the combined ticket doesn't save you money, but it gives you room: three days to take it slowly and, once the Algepsar Cave reopens, a fourth site included. If you're staying overnight in Onda, it's the easiest option.
There is also a €10 pack that combines a dramatized visit with the combined ticket. Children up to 6 don't pay for this option either.
Dramatized visits
These are guided tours in which actors recreate historical scenes in the sites themselves. They cost €8 with admission included, and you need to sign up beforehand at Tourist Info. These are the next scheduled dates as of 29 September 2026:
