There are a few nice coasters here in the Netherlands....
In 'de Efteling' (the best known dutch themapark) there is:
- Python, it was the fastest coaster in europe when it was built (decades ago), recently it hit the news with a ****up by the crew, allowing the coaster to do a run with safetyharnesses not engaged.

- Pegasus, a nice small wooden coaster, I was in the park one day when it was really quiet, and they had it run 17 times in a row without stopping, great fun!

- Vogel Rok (named after the Rocs, the giant birds from the tales of Sinbad), indoor coaster in darkness with some nifty light effects and a nice soundtrack.

- De Vliegende Hollander (the Flying Dutchman), a combined coaster/water ride. Inspired by the legend of the flying dutchman. The buildup of tension on this ride is great, and decor is beautiful, but the ride itself is a bit of an anticlimax as it's too short.

- Bob, not really a coaster, but a bobsled, still fun tho'.

- Xpress, Tight corners, climbs and drops. This coaster has a very small footprint for its track length. No going uphill first, you get launched from the starting point.

- Flying Dutchman Goldmine, this one has little to do with the legend of the flying dutchman. It was inspired by the racing Mine cars you often see in movies.

- El Condor, Suspended under the track, inverts 5 times throughout the ride.

There are a few more themeparks, but none of them have very special coasters. A few other coasters on this side of the big pond that deserve a honorable mention are Space mountain: the 2nd mission, Big Thunder Mountain & Indiana Jones and the temple of Peril in Disneyland resort Paris, Anaconda in a themepark near Metz, france (it changed name so often that I really dont know what its called these days) this coaster is kind of special, as it is the biggest wooden coaster in europe and can reach speeds up to 110km/h, which is pretty darn fast for a woody....
