Fodor's Expert Review Castelo de Almourol
For a close look at this storybook edifice on a craggy island in the Tagus River, take the 1½-km-long (1-mile-long) dirt road leading down to the water from the N3. The riverbank in this area is practically deserted, making it a wonderful picnic spot. From here, a small motorboat will ferry you across (€4 round-trip); for a more leisurely river cruise, board a larger vessel (€2.50) at the quay just downstream in the village of Tancos. The sight couldn't be more romantic: an ancient castle with crenellated walls and a lofty tower sits on a greenery-covered rock in the middle of a gently flowing river. The stuff of poetry and legends, Almourol was the setting for Francisco de Morais's epic novel Palmeirim da Inglaterra (Palmeirim of England), about two knights fighting for a princess's favor. In 2015, a small museum was opened inside the keep.
