Wildlife is most active at dawn and dusk, exactly when hotel guests have not yet arrived or have already left. With a motorhome you can sleep on a nearby campsite or aire and be at the viewpoint first thing, coffee made and binoculars ready. From the Segimon Rental base in Granollers, both the Ebro Delta and the Pyrenees are just over two hours away.
The golden rule is distance: keep away from nests and young animals, stay on marked paths, never feed wildlife and keep dogs on a lead. Leave the drone at home, as drones are banned in many protected areas. Spring and autumn are best for migrating birds; summer for high-mountain wildlife. No sighting is ever guaranteed, but with patience and a bit of luck the reward usually comes.
