Puerto Cancún is a mixture of residential, commercial, and tourist areas. An 800-acre upscale development next to the ocean featuring a large marina, a golf course, a waterside promenade with a luxurious outdoor shopping complex, eateries, and cafés, as well as hotels.

A 20-minute boat ride from Cancún lies the small island of Isla Mujeres with its laid-back Caribbean ambiance, tiny streets lined with stalls, and street cafés in pastel-colored houses. Golf carts and mopeds dominate the streets, and although the island is only 5 miles long and half a mile wide, it still offers plenty of things to do and see. Everything from a beautiful palm-fringed white beach on the north coast to a dramatic rocky shoreline on the eastern side to a sea turtle sanctuary and the remains of a Mayan temple at the southern tip. If you're into adventure, then you should visit the Garrafon Reef Park & Beach Club, where you can go zip-lining, snorkeling, and kayaking. Lastly, a must-visit for nature and wildlife lovers is a tour to Isla Contoy, a nature reserve only inhabited by a few biologists and restricted to 200 visitors per day.

This small and elegant mosque is one of Tirana's oldest surviving structures. Closed during communist rule, it reopened for worship in 1991 after being shuttered for decades. Many religious sites were destroyed during the atheism campaigns of the 1960s, but this mosque was spared. Its distinctive frescoes, found both inside and outside the portico, depict nature scenes like trees, waterfalls and bridges, which are unusual motifs in Islamic art.

After passing under the round City Tower, the former main medieval town entrance that gave access to the coast, you'll enter the centre of Rijeka's Old Town. Located in the modern-day Ivan Kobler Square, there was once a more compact municipal centre called Placa, which served the significantly smaller fortified medieval town.
