These romantic 19th-century landscaped gardens are free to visit and offer spectacular views of Porto, Gaia, and the Douro River. Spend some time wandering the maze-like gardens, populated with luscious trees and flowers, take a couple of pictures, and then stop by one of the many fountains to admire the free-range peacocks.

Igidae Coastal Walk makes for a wonderful hike along the shore of the Sea of Japan. The path itself is of moderate difficulty, with some parts featuring pedestrian bridges and others running directly through natural terrain. The entire path is about 4km long and should take about 2 hours to complete in its entirety, but there are access points along the way which you can use to cut through to a nearby bus stop. The trail can be done both north to south and vice versa, although heading north is reportedly easier and comes with an added bonus of finishing the hike at the scenic Oryukdo Skywalk, standing on a see-through platform and looking down onto the rocky shore.

Hosted within the Benedictine monastery of St Mary, this permanent exhibition of religious art is one of the most valuable in Croatia and displays a number of masterpieces made out of gold and silver, but also other precious items such as manuscripts, embroideries, reliefs and tapestry.
