At just over 430 metres high, Pico do Castelo feels a little different from the island’s other viewpoints. It’s greener, quieter, and layered with history. The summit is dotted with conifers, a rare sight on an otherwise dry island. A cannon and the remains of a 16th-century fortress, built to protect the population from pirate attacks, mark its past as a defensive lookout. You can reach the top either as part of the PR2 hiking trail or by tackling the short, steep climb from Vereda do Pico do Facho, which takes about 15–20 minutes on foot. The payoff is a wide view over much of Porto Santo, and on clear days, even Madeira on the horizon.

Whether you decide to take a walk on the river banks or to book a cruise, which you can combine with lunch on board, the Garonne offers plenty of sights for a delightful afternoon or early evening. One company that offers cruising activities in the city is Les Bateaux Toulousains and they have three boats located at Port de la Daurade, Port de l'Embouchure and Port Saint-Sauveur.

The Château d'Eau, a 19th-century brick water tower located on the banks of the Garonne river was once used to supply 90 fountains. It has been repurposed as a photography gallery hosting exhibitions and a library selling books on photography.
