The lively and friendly atmosphere of Parque de las Palapas is worth a visit, especially on the weekend evenings. Watch a local performance on the open-air stage, browse around the artisan stalls, visit one of the bars and cafés around the park, or just come here to observe and soak in the atmosphere. Just across the adjacent car park, next to the church, you'll find the so-called "Hippie Park" offering hand-made jewelry, lamps, and tie-dyed clothing.

Ponte Dom Luís I (The Dom Luís I Bridge), one of Porto's most famous landmarks, is a 172 metres double-deck metal arch bridge--the longest of its kind in the world--and links the cities of Porto and Vila Nova de Gaia over the River Douro. It is well worth a visit, especially to admire the sunset.

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.
