Get a glimpse of Borneo's unique endemic primates — proboscis monkeys — and marvel at the beauty of nature. On this guided tour, you will see local fauna in their natural habitat, followed by an unforgettable sunset. Once the sun sets, trees fill with fireflies, creating a picturesque scene.

The preserve is a county-run park offering public access to a four-mile loop that allows hikers, bikers, and horseback riders. A collection of rare animals also make their homes in the area: Stephens' kangaroo rat, fairy shrimp, purple stipa, blue-eyed grass, and wooley blue curls are just a few. Bird watchers will enjoy the grand hawks that live in the grasslands as well.

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.
