Urk is in Flevoland. This former island is situated on the edge of the Noordoostpolder and directly connected to the IJsselmeer. Because of this people in Urk still talk about living 'on' Urk instead of 'in' Urk.
There are only busses going to Urk from Emmeloord and Lelystad but the former island is near the A6 highway. In the summer you can take the ferry from Enkhuizen. Urk has a small harbor which is directly connected to the IJsselmeer, on Sundays you can use the harbor for free, on all the other days you have to pay a small fee.
Urk is just a small town, only 17.000 inhabitants, and everything you would want to see there is within walking distance of the harbor. Or you can rent a bike of course, but if you plan on staying on Urk you can do without one.
Urk used to be an island and still is a very traditional fishery village. There is a lighthouse, a fishery museum and the old part of the town is still very authentic and pleasant to walk around in.
Outside Urk there is a stone reservation. A place where a lot of stones which were laid there during the last ice age can be seen.
When you come to Urk make sure you try some fish. There are several restaurants of which one, Mes Amis, is in the top 50 of Netherlands's best restaurants.
Urk doesn't have any hotels but there are a lot of hostels you can spend the night. There are also quite a few bed and breakfasts in the old part of the town.
