East of Karachi lie the Chaukhandi tombs, a vast Islamic burial ground full of incredibly ornate tombs that date back to somewhere during the 15th through 18th centuries. The sandstone structures are believed to be a burial site for the late Jokhio tribe members.

Knez Mihailova Street is the pedestrian area that unifies Belgrade's beautiful architecture. It leads to the Belgrade Fortress and Kalemegdan Park on one end, and to Terazije and the iconic Terazijska česma drinking fountain near Hotel Moskva on the other, offering a splendid view of the Sava river valley. Inside tip: Take a detour to Kosančićev venac, the oldest part of Belgrade outside the fortress. This charming elbow-shaped street is home to Princess Ljubica's Residence, the Building of the Patriarchate of the Serbian Orthodox Church, and the Cathedral Church of St Michael the Archangel, all of which are sure to captivate you with their elegance.

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.
