Amazing place! To…read morepreface, we were just your average tourists, unlike those who "pilgrim" their way here (hats off to those hardcore hikers). Nevertheless, breathtaking! Maybe not as grand as the Vatican, but after being to both, I love this cathedral much more... Great views, great vibe, great mass (if you're into such a Catholic thing), and a great cobblestone surrounding city to get your walk on... It's amazing! If you've never, you should! Prost!

Clearly this is a must-see site if you visit Santiago de Compostela.

However, during our trip in early September, it only took us about 15 minutes to enter around 4 pm. So, it might be worth it to visit later in the day. In addition to viewing the wonderful Romanesque interior, you can also visit the tomb of St. James. Be aware that there is another line to view the tomb. Also, it's set up where you are not really allowed to linger around the tomb because it's pretty much a walk in, walk out situation. Admission is free for both the cathedral and tomb. Also, are not allowed to bring large rucksack; however, you can bring smaller bags.

At the very top, there is a small gift shop with lots of souvenirs you can purchase. I've been on the pricey side, but the free admission makes up for it. There's about 8 to 10 stairs to climb down or up depending on where you start. In the middle of each stair, there's something to look at her to get a picture of. At the top, you can also see the little carriage that was used back then to transport people between the levels. The bathroom nearby is not free, unfortunately.

This World Heritage Site is the world's only complete Roman Wall still standing, and offers 360-views of the city by day and night over about a mile loop. You don't need to pay or get a pass to walk on it--completely free and accessible to the public at any time. I loved to jog around it every night (super safe even after dark); it felt like running on an elevated track/boardwalk around the city that just happens to be thousands of years old.
