QECP is good.
There's two main trails, red and blue. I tend to do the both, starting with the red. It's just over 9 miles and takes about an hour and a half.
The red had steep rooty climbs with some fun descents, berms, a few drop offs and jumps but nothing massive - no gap jumps or tabletops or anything like that.
They've just added a new section which is quite cool. The biggest issue is that the bigger, more technical berms are exposed chalk so they're bumpy, errode quite badly and are lethal when wet. The rest of the red trail is rooty and muddy, so slippery when wet but good in the dry.
The blue has a longer but easier ascent. The first bit is rooty but the majority is packed hardcore. It's less technical but you can get some serious speed on the decents and there are some cool linked berms.
There's a section in the middle that has a little jump (where I crashed yesterday) and a few rollers which is usually great (if you don't crash).
A lot of people climb the blue and come down the red which is a good way of getting into it, but the red climb has some nice little down sections that you'll miss if you do it that way.
I went nearly every week last year and it's a bit of a mixed bag. In the winter it's muddy and slippery and usually wet. In the summer it's usually dry but if it's too dry the mud-dust reduces grip. In the summer the tree canopy also makes it hard to see in places. In the autumn all the leaves fall and the trail is hard to find and also slippery... the best time is really spring when it's dry and sunny but before the trees are in full leaf. However, I don't want to put you off - it's always good fun!
If you want more downhill challenges there's always Stoughton downhill which isn't far away.
