I am not sure what to think about this park. It has something for everyone (small beach, good for…read morerunning, cycling etc), and there are sport fields (mainly field hockey)
I am a new resident to IJburg, and not familiar with the history of the park, until I looked into that for this review. This used to be a landfill, even for chemical waste. Mid 1990's the area was completely remediated and isolated. The area is under constant active control to make sure that everything stays clean.
The impact of all of this is clearly visible in the terrain: there are no large trees (the roots would penetrate the isolation layer), and there are concrete wells clearly visible throughout the park.
Anyways, back to my review. You can run, skeeler and cycle here perfectly. The quality of the roads is good, and since there is no traffic, you can do your thing in peace. There are a couple of grass fields where you can play some sports, or even do Yoga if the weather is good.
So why am I giving just 3 stars? The park is big enough to also allow for a dog park, however, dogs are only allowed off lead on a few small grass strips at the edges of the park. MIssed opportunity for all the dog owners on IJburg :(. Also, this island is owned by rabbits. It must not be nice to play any kind of sports on the grass fields, that are covered in rabbit holes. Unless you want to break your ankles of course. Lastly: I understand why there is no light on the park, however, it would give a safer feeling at night (when cycling or running there), to at least be able to see where you are going.
