Generally, on Thursdays at 9:30 am, the visit is into one of the English telescopes (WHT or INT), while the other tours take place at Gran Telescopio Canarias (GTC). The Observatory reserves the right to modify the days and times of the tours, as well as the visited telescope, depending on its availability or due to causes outside the sphere of its foreseeable control or events of force majeure.
