I have visited a lot of places in my country, as well as in Europe. 
Between all these places, I have been delighted by these eight ones that I describe in my google list. A common characteristic is that all of them are related to nature, and I am very content with that, because I love recycling, and I think it would be a great idea if everybody takes care of the environment. 
At my profile, you can find a post related to each place! Hope you enjoy it.
- Genal Valley, Málaga, Spain.
- El Torcal, Antequera, Spain.
- National Park Monasterio de Piedra, Zaragoza, Spain.
- National Park Cabañeros, Ciudad Real, Spain.
- Center of Seville.
- National Park Las Tablas de Daimiel, Ciudad Real, Spain.
- Plaza de España, Seville, Spain.
- Novo Sancti Petri, Cadiz, Spain.
Anyway, I have started with this list, but I intend to increase the set of sites in the near future.
