Besides these specialized centers, organized visits can be easily found in travel agencies and in many of the city's hotels who have agreements with tour guide agencies for its guests.

On the other hand, museums and historic or tourist areas offer guided visits directly at the site. Tours can only be given by accredited and authorized personnel.
