Just outside Palau, less than an hour north of Olbia, you can find Fortezza di Monte Altura. This 19th-century fortress has seen many wars, but has remained largely intact. From the fortress, you will have a stunning view over Palau, Corsica and La Maddalena. It is highly recommended to take the guided tour.

Built for the 1962 World's Fair, the Space Needle is 605 feet high with an observation deck at 520 feet and the rotating SkyCity restaurant at 500 feet. From the top of the Needle one can see not only the Downtown Seattle skyline, but also the Olympic and Cascade Mountains, Mount Rainier, Mount Baker, Elliott Bay and surrounding islands.

Downtown (El Centro) is the actual backbone of Cancún. What it lacks in history, it makes up for being a true melting pot — an exciting mix of the old traditional Mexico and an ultra-modern urban sprawl. Avenida Tulum, the main street, passing through the heart of the city, is easy to reach by public transport. The street is lined with shops, cafés, bars, and restaurants. Be sure to stop by Parque de las Palapas, on the market square, where locals come to chat and watch the entertainment provided by various local groups. The lively atmosphere and the sound of Mexican music are infectious, and any worries will quickly be postponed to "mañana." Browse around the artisan stalls and try some of the local sweet delicacies or visit the "Hippie Market" around the corner. In the evenings, the place to be is Avenida Yaxchillan with its lively restaurants and bars, popular with locals and tourists alike.
