Singletrekpodsmrkem as mentioned is brilliant. Not uplifted though. It’s more like a Coed Y Brenin or something.
Also in Czech, Spicak bikepark is really good.
I’ve been to the parks in Andorra – Really great…
Saalbach is awesome in Austria.
Beerfelden and Gieskopf in Germany are brill.
Gieskopf particularly has a trail called the Flow trail which is about the most fun I’ve had on a bike.
Flowy, jumpy smooth for ages and ages. So much fun.
Morzine, Les2Alpes and Alpe Duez are all great, and lots of lesser known ones too in France.
The Swiss ones are good. Morgins being a favourite.
Any in particular you were looking at?
