Travel companions for wildlife observation trip in Asturias early May

Two nature enthusiasts in their sixties are planning a naturalist stay in Asturias: hikes, wildlife observation (Cantabrian brown bear), local architecture, and a return trip through the plains of Villafafila (lagoons and birds). We have observation equipment and knowledge of the area. Accommodation will be in a rural hotel. Departure planned for May 4th from southern France, returning on the 13th by comfortable car that can carry 1 or 2 additional companions.
