Covadonga

To see high alpine meadowland, some rare Spanish lakes, and views over the peaks and out to sea (if the mist ever disperses), take the narrow road up past Covadonga to Lake Enol, stopping for the view en route. Starting to the right of the lake, a three-hour walk takes in views from the Mirador del Rey, where you can find the grave of pioneering climber Pedro Pidal. Farther up the road from Lake Enol are a summer-only tourist office and Lake Ercina, where Pope John Paul II picnicked during his 1989 tour of Asturias and Galicia.
