Yes, there is the 'Park Güell and schools' program, which offers educational centres from EU countries the chance of visiting the restricted area with a guide specialised for your age group, or unaccompanied as long as a series of requirements are met.

Access to the regulated area of the park with companion animals (pets) is only permitted if the animals are duly secured on a lead (in accordance with the Byelaw on the Protection, Possession and Sale of Animals (OPTVA)). Visitors can access the entire park with their pets, except for Nature Square, Hipostyle Room, the Dragon Stairway, the Austria Gardens, Gaudi House Museum and the Laundry Room Portico to ensure the safety and protection of people, pets and heritage. People who own or accompany pets shall be responsible for any damage that those animals may cause.
