In the last decade, more and more with , , , to name but just a few. At the same time however, a wide range of leisure activities has also come about, that focus more on contact with the environment and science than tall, twisting roller coasters.
 
Of the many centers connected to nature in Spain, the most classic are the zoos, which allow children to see animals without leaving the city. The , one of the most important in the world, contains a dolphin tank, aquarium, a large aviary and a zoo with more than 500 species of animals, among which the koalas, the zoo's latest acquisition, stand out. The is still among the best in Europe, despite the loss of its most cherished symbol: "Copito de Nieve", the only known white gorilla in the World.

In terms of aquariums, Spain boasts the largest one in Europe, the spectacular . It recently celebrated the first birth of a gray shark in captivity. Every Saturday, the , as part of its Escuela de Científicos (school of scientists) program, invites children between the ages of 4 and 14 to do little research projects, which are accompanied by a delicious snack.

Another option available to children are the big nature parks such as , Selwo, on the Costa del Sol or . The first of these, with a surface area of 140,000 square meters, reproduces the world's major ecosystems, and also has an interesting nocturnal room, where you can observe nocturnal species without being seen. As for Selwo, it focuses a little bit more on adventure, and has two sites: one in dedicated to birds and land animals and the other in , which specializes in marine animals. In an enclosure inhabited by over 500 animal species from the seven continents, Valwo combines leisure activities with environmental education. 
 
Along the same lines, but giving a greater role to adventure, we find safaris, where animals are not caged and for which a car is essential. At the Safari Park in Aldea del Fresno, located an hour from , you can travel among elephants, rhinoceros, hippopotamus, giraffes and many other species.

However, if you would like for your children to see animals in their natural habitats, other possibilities include natural parks. Cuenca Alta del Manzanares, in La Pedriza (Madrid), organizes guided tours for children on weekends and holidays. Accompanied by guides, children learn how to identify different plant species, and discover the hiding places and habits of squirrels, griffon vultures, roe deer and more.

Further north in the Centro de Interpretación de la Naturaleza (Interpretive Center on Nature) provides organized visits to observe the rich variety of bird life present on the region's lakes. Still further north, in Asturias, a fun option is the a pleasant route along an old railway line that stretches between the towns of San Andrés and Teverga. While traveling, on foot or on bicycle, one of the most beautiful regions of Asturias, children can meet "Paca" and "Tola", the two brown bears that live in the area.   
 
Returning to the city, and in a more scientific vein, museums can also be the perfect way for children to have fun while they learn. A classic example is the , which periodically organizes activities to help the little ones keep abreast of the latest scientific discoveries. And in Valencia, the at the  offers El cielo de estrella, an audiovisual display in which children learn how to identify the major constellations.

The is a great place to learn about the origins of human beings, and suggests guided itineraries that recreate the fauna of the Pleistocene period, huts from the Paleolithic period and settlements of the Bronze Age. All to entertain and teach children about prehistory. Not far from there, in the provinces of and , there are a variety of routes that lead to archeological sites containing the remains and footprints of dinosaurs.
