Sounds a bit like Leeds
VFR traffic all leaves the zone at or below 2000ft through the VRP's
IFR comes in at 3000ft+
Yes it is bloody dangerous I have come way to close to various bits of traffic going both ways over Eccup. It wouldn't be so bad but the viz at Leeds is usually pants. And a twin coming at you at 5km if your lucky with a combined speed of 200+ knots aint fun.
And as for that VRP to the south which is at the bottom of a valley I still haven't yet been sure I have found the sod. Funnly enough tho you don't meet much traffic coming through there. They must cheat like I do and get one of the easier VRP's further north. Or radar vectors.
