Haven’t been to QECP but ride Punchbowl a lot (and Peaslake)
Punchbowl is actually quite tricky to find not least because the best stuff isn’t in the Punchbowl and the main bit is not meant for bikes anyway (there are a few bits on either side that I ride, one obvious and ok, the other cheeky and hard to find)
But the best stuff is on the Gibbet Hill side and the Bomb Hole ridge beyond the temple of four winds or winds (can’t remember which). Sme of it is q steep (and beyond me) with some hidden jumps and drop offs. There is a semi-hidden area q close to the well known Gibbet stuff which was ignored for ages*. Now been rediscovered with new routes, drops and berms being built and now that it’s more serious new chicken lines. Which is a shame as its going to get spoilt. I showed this area to two ballsy riders about 6 weeks ago, so maybe I am to blame indirectly.
* used to feel like millionaires MTB as hardly ever saw tracks other than mine for most of last year. Three trails, one beyond me and scene of very painful face plant and lots of blood! Now my favourite run is being up-graded above my comfort zone and many new lines appearing each week!
