The Georgia Aquarium is one of the largest in the world and a major attraction in Atlanta. It is home to thousands of animals of several species, including beluga whales, great hammerhead sharks, penguins, and puffins. Don't miss the spectacular dolphin exhibit and the dolphin show.

More than just a bookstore, Livraria Lello is a historical and architectural masterpiece in downtown Porto. Opened in 1906, Livraria Lello & Irmão as it is also known combines elements of Neo-Gothic, Art Deco, and Art Nouveau styles that comprise intricate woodwork, a large stained glass window bearing the bookshop monogram with the motto "Decus in labore" (dignity at work, in Latin), and a remarkable red spiral staircase, which starts as one set of stairs and splits into two that join in a circular design. The latter is a huge attraction here since it resembles the Grand Staircase from the Harry Potter films, and considering J.K. Rowling was once a Porto resident, there is a high chance this place might have inspired her. Livraria Lello became so popular with tourists that in July 2015 the store started charging a 5 Euro entrance fee and queues can take over an hour. You can purchase tickets on their website.

Currently the headquarters of the municipal company Águas do Porto, hence its second name Parque das Águas (Water Park), the Nova Sintra Park is one of the largest green spaces in Porto, boasting great botanical diversity, dense trees, as well as a peaceful atmosphere--a nice place to relax and take a break by one of its many fountains.

Colombier Beach is St Barts’ crowning escape — a crescent of white sand accessible only by boat or two scenic hiking trails, ensuring its pristine seclusion. The Flamands Trail (20-30 minutes) starts past Petite Anse, winding along cactus-dotted cliffs with glimpses of rocky shores. For panoramic vistas, take the Colombier Lookout Trail (30-45 minutes) from the viewpoint parking lot, descending past iguanas sunning on volcanic boulders to reach the shore. Protected by a hilly peninsula, the bay’s calm waters reveal sea turtles and coral. Don’t forget to pack your snorkel! History lingers at the western edge, where hurricane-topped ruins of Laurence Rockefeller’s 1950s villa stand guard. No facilities mean packing sun shelter and water; early mornings reward hikers with empty sands and gentler heat.
