Tarragona

The 2nd-century AD Roman amphitheatre carved into the seaside promontory, with capacity for 15,000 spectators at its peak. The fenced interior is closed to non-assistance dogs, but the surrounding park and the upper viewpoint stay open and offer one of the most spectacular leashed walks in Catalonia.

The wrought-iron-railing balcony at the end of the Rambla Nova, with views over the Mediterranean and the amphitheatre. The most photographed viewpoint in Tarragona, open 24/7, leashed dogs welcome; Catalan tradition says you touch the iron (tocar ferro) for good luck.

A 1 km shaded promenade between the inner Roman walls (3rd century BC) and the 18th-century outer fortifications, with viewpoints, lawns and watchtowers. Outdoor, on a leash, perfect when combined with Camp de Mart to circle the whole wall.

Tarragona's largest urban park, 32 ha along the Francolí river, with a fenced àrea d'esbarjo per a gossos (off-leash dog area), flat paths and a riverside pedestrian promenade. The local daily walk, 15 minutes on foot from the Rambla Nova.

East of the city, Platja Llarga (3 km of sand, designated dog area) extends the Costa Daurada coast; a path through the Bosc de la Marquesa pine forest leads in 20 min to Cala Fonda, the unsupervised cove and local dog-favourite, open year-round.

The 12th-century Romanesque-Gothic cathedral crowning the Part Alta. The interior is closed to non-assistance dogs, but the open-air cloister and the surrounding square are leashed-dog accessible and offer one of the calmest viewpoints over the old town.
