This is a beautiful not very well known National Park of Spain. Roads are very good there due to heavy EU funding. Things to see and do: motorcycling!!!! canoeing, mountain climbing, trekking...
The park lies in the asturias next to the so called green coast of spain, there is always a good chance to get some rain. It is also next to the jakobsweg an old pilgrim route and near to bilbao (guggenheim museum) and santander.
