  • How to play?

    We have two types of routes: The Treasure of Al-Muqtadir and the simple routes.
    In the case of the Treasure of Al-Muqtadir, the route goes through the main cities of the Pre-Pyrenees. In them, and through a series of clues that we have left on the website, you will be given a number with which you will unlock through the web a GPS address where there is hidden part of the treasure of Al-Muqtadir.
    The simple routes, in which there is a common theme such as Lost Trades or the Sepharad Route, are a walk through different villages, in each one there is a hidden treasure that you must find with the help of a GPS.

    All locations are geolocated through the free mobile application

    What do I do when I find the treasure?

    When you find it you must sign the sheet included, you must also put it back in its place, remember that we all want to play, and it is very frustrating to arrive and not to find anything because someone has taken it. And remember that you can take part of the treasure, as long as you leave another one in exchange, for that reason it is important that you take small pieces, toys, badges, or whatever you can think of to exchange.
