With steep streets and villas staggered up and down the hillside, Albufeira resembles a North African seaside community. The big, bustling resort town rises above a sickle-shape beach that shines in the bright sunlight. A rocky, grottoed bluff separates the strip used by sunbathers from the working beach, where brightly painted fishing boats are drawn up on the sand. Access to the beach is through a tunneled rock passageway.
After walking Albufeira's often hot but intriguing streets, you can escape and cool off at Zoo Marine, N125, Guia (tel. 28/956-03-00; www.zoomarine.com), 6.5km (4 miles) northwest. It's a popular water park, with rides, swimming pools, gardens, and even sea lion and dolphin shows. It's open Tuesday to Sunday 10am to 6pm. Admission is 22€ ($28) for adults and 13€ ($17) for children 10 and under.
