Since its conception, environmental education has carried out numerous plans, strategies and programmes aimed at restoring an adequate person-nature relationship, addressing the main environmental problems that threaten the planetary ecosystem balance. Even though environmental education proposes an integral education, it is infrequent that the spiritual dimension of the person appears reflected in its programmes. However, spirituality, which often manifests itself by providing affect and meaningful significant life experiences, aims to be a key factor in the development of lasting pro-environmental behaviours. Promoting and valuing ecological spiritual intelligence is configured as an interesting advance for environmental education. For example, starting from the cultural-naturalistic values provided in every part of the territory. As an example, we propose the one made in the Basque country (Spain), using the spirituality contained in the Basque mythology.
