Given that the Spanish Railways Foundation (SRF) does not have an open office to the public, we can not guarantee a personal reply to your messages (we receive hundreds every week) but it will be readed carefully. We welcome your comments and suggestions.
If your question relates to a specific greenway, it will be sent to its manager so he can meet your demand.
¡¡Fortunately, we have much work trying to create more and better greenways!. Thanks for your understanding
