Know Before You Go
The entrance is at the Garden Side of the Sanctuary. Guided tours (the only way to visit the Crypt and the Heavenly Tower) are from Monday to Friday, from 10:00 to 1:00, being subject to some exceptions depending on church celebrations such as baptisms, first communions, weddings, etc. Days celebrating special dates, like the Day of the Immaculate conception, Maundy Thursday or Good Friday, etc. are also excluded.
As of July 2018 the parish priest is wanting to stop all visits if he can and the tower will also close soon to be renovated, so it may be closed until late 2019. It is truly worth seeing this marvel ASAP.
