Have been about 3 times. Twice in the dry, once in the wet.
It’s lethal in the wet as it’s very chalky. But enjoyed it in the dry.
I can ride most stuff at UK trail centres but found Tidworth quite hard. Mainly due to the steepness.
There’s a couple of easier runs (I think single orange grade so broadly equivalent to blue). But i found them steeper than any other blue I’ve ever ridden
Almost everything on those runs is rollable or avoidable, apart from a couple of smallish drops.
I ended up just sessioning a few little drops or berms rather than pushing back up for the full run. But that was midweek at lunchtime, so really quiet.
If you are looking to practice your skills then it’s worth a visit.
Hope that helps.
