Practical information : Sightseeing Malta
Some of Malta's sites and museums are brought together under the umbrella of Malta Heritage. Most are closed on Monday and Tuesday and open from 9am to 5pm. But this can vary between museums and sites (check their websites at the last minute) and according to the season. Generally speaking, everything is closed on 24, 25, 31 December,1 January and Good Friday. Groups prefer morning visits, so avoid them if you want to be quieter
To be booked
If you wish to visit the Saint-Jean co-cathedral in Valletta, you do not have to make a reservation but as the queues are quite long, it is best to plan your schedule of visits by setting a time for it first. On the other hand, it is well in advance, at least two months, that you will need to book to visit the Hal Saflieni Hypogeum. Visits are limited to groups of 8 people, i.e. a maximum of 64 visitors per day. So plan ahead as soon as you decide on your trip, otherwise, once you get there, it won't be possible
Budget & Tips
In Malta, the most expensive thing you can do is to enter the Hal-Saflieni Hypogeum (€35 for an adult). Most of the other sites and museums managed by Heritage Malta vary between 5 and 10 € for an adult. A multi-sites pass is available (see conditions on the website https://heritagemalta.org, under "admission fees") but it does not include the entrance to Hal-Saflieni. Do not hesitate to list what you will have time and desire to see to decide if this pass is interesting. Many churches are free to enter, with the exception of St John's Co-Cathedral (€15 for an adult), Mdina (€10 for an adult) or Victoria in Gozo (€4 for an adult). The prices indicated in this guide refer to adult rates but various discounts are almost always offered for children, seniors, students and even families. Do not hesitate to ask for information when buying your tickets
Please note that the monuments are closed at Christmas, New Year's Day, Good Friday and on Maltese public holidays.
