Running through the heart of Utrecht, the Oude Gracht ('old canal') is the major artery of the…read morecity. It's lined with many shops at street level and bars and restaurants at the level below. It also hosts a weekly flower market on Saturday morning. Yes, it can get a tiny bit seedy at night with rowdy students ('bralapen') and it isn't always as clean as one would like, but this all adds to the charm. It's truly a wonderful place to hang out any time of day or year. The oude gracht was built in the 1100's by upgrading and taming a former branch of the River Rhine. The mooring level (accessible by steep steps from road level), where goods would be loaded and unloaded, gives access to deep tombs / caverns that extend below the road and under the shops above. In the old days used for storage, they have now mostly been transformed into bars and eateries. It's hard to miss the oude gracht when you're in Utrecht as many of the city's landmarks, including the Dom tower / church and various museums are located close by. Enjoy this place. It's awesome. But, be careful of bicyclists as you stroll around; you'll likely have your eyes on façades or the water below!

I started my Amsterdam trip with a tour of Koninklijk Paleis. The Palace is located in Dam Square…read more Tickets are €12,50 and I was able to walk up and purchase a ticket at the main entrance. They have a free coat check which was useful. I did the self guided audio tour and I think I spent about 1.5-2 hours. The palace was built in the 17th century and it initially served as the town hall until Louis Napoleon claimed it as his palace. Now it's used for state visits. The palace is one of three residences of the royal family, however their primary residence is in The Hague. The architecture is beautiful. I really enjoyed Citizen's Hall. The self guided tour focused on the art and architecture while giving a history of past monarchs. It was kind of crazy walking through a room where executions were once carried out. I would have liked more information about the current royal family (King Willem-Alexander and Queen Maxima). I learned on a different tour that he is a pilot and occasionally flies for KLM. I didn't enjoy this tour as much as I thought I would. If you're short on time, I would recommend skipping the Palace.

It's has 465 steps, and you will be able to see old and new bells, and will enjoy a nice view from the top of the tower. The entrance was 9 euros in June 2016, 7.50 for concessions and the tour is conducted in Dutch and English. In our case, Dutch visitors didn't mind it to be English-only, so the tour was in English. You are required to leave your things in storage cameras (you can take a photo camera), however, as it was a hot day they allowed us a bottle water as well.

The tower is quite impressive to see and has amazing architecture work. Unfortunately during my visit to to Utrechet, they were remodeling the outside of the tower so I wasn't able to see all of it since it was covered up. I really wanted to go inside the tower but the only way they will let you in is through a guided group tour, something I didn't feel like waiting around for. Cool building nonetheless, a great sight to appreciate even if you don't go inside.
