Sintra's palaces require radio guides for more than ten visitors per guide, and you bring your own (2026)

Inside the palaces run by Parques de Sintra, a guide with more than ten visitors must use a radio-guide system, and must bring it. The company's rules for guides have required this since 15 May 2023, and its page for tourism professionals says radio-guide rental for groups is suspended. Quinta da Regaleira, run by a different foundation, keeps external guides out of its palace and well.

Rule 3.2.4 of the "Regras e Condições de Utilização por Guias" makes a radio-guide system mandatory for groups of more than ten visitors per guide in all indoor spaces. The same section caps visitors per guide, bans stopping on the Pena route and ties admission to a professional card.

The document states it is in force from 15 May 2023. Rule 3.1 adds that Parques de Sintra reserves the right to allow guides into the spaces it manages, so these conditions decide whether a guide gets in.

No. The Parques de Sintra page for tourism professionals says radio-guide rental for group visits is suspended and that external guides must bring their own equipment. The company does not supply receivers to groups, so the system is the guide's or the agency's responsibility.

Visitors per guide, not the guide. The rule counts "visitantes por guia", so on its wording a group of 22 with two guides has 11 visitors per guide and needs radio guides, while 20 visitors with two guides stay at ten each. The caps work the same way: 25 per guide at Pena, 50 at Sintra and Queluz.

Quinta da Regaleira is run by the Fundação CulturSintra, not by Parques de Sintra, and its rule is stricter: external guides may not lead guided visits inside the palace or the Initiation Well. The estate rents its own audio guides at the ticket office for 5 EUR in 2026.

The foundation's visit page publishes no restriction on guiding in the gardens. Explain the palace and the well before the group goes in, let guests walk the one-way route on their own or with the estate's audio guide, and meet again outside. A phone-based system does not change this: inside those two spaces, external guiding is not allowed at all.

The foundation can end a visitor's stay without refund for breaking its visiting or safety rules.

The rules say "sistema de rádio-guia" and stop there: no frequency, brand or number of channels. Whether a phone-based system is accepted as one is for Parques de Sintra to confirm, and the address to ask is b2b@parquesdesintra.pt, the same one that issues guide cards.

Your Next Tours uses no dedicated receivers. The guide's phone streams over a pocket WiFi router, and guests scan a QR code and listen in their phone's browser through their own earphones. No internet connection is needed during the visit, and the audio runs one way. Ask whether that setup is accepted as the rádio-guia the rules require, and keep the reply with your card.

In Sintra the rules expect the guide to bring the system. Create a tour in the guide app, share the QR code before the palace door, and see how the broadcast works and our pricing. Our world overview lists the Parques de Sintra rule and Quinta da Regaleira with other countries' rules.
