(I have only visited twice but plan to go more often now I am closer)
Overall Swinley Forest has extremely well built trails and is great for beginners and slightly advanced, however it needs more variety and options ;)
Definitely needs more trails another blue and another red and a black. Some short red diversions for people wanting to try some red that can go back to blue. Swinley Forest is already very popular and can get pretty over crowded at times, I feel this could be a even bigger and better place with the added suggestions and more trails would take some pressure of the current trails.

What could be improved?
If you are looking for technical or advanced this is not the place as of yet! Better sign posting around the trails
Swinley forest is a short ride from home so I visit about 4-5 times a week. I ride the blue and red about 4-5 times a week and I haven't got bored yet! I don't enjoy 10" jumps and "no fitness required" downhill cycling though.
What do you like?
The trails are well managed and maintained. Great for novice to intermediate riders and for those wanting to keep fit.
What could be improved?
If you're wanting some real adrenaline and big jumps you'll be better off going to trail centers dedicated to this.
If you love just blasting around without the fear of a 10 foot drop off or jump in you way as you speed around then this is your place. I think for bike park training it's fantastic to build up your handling skills and fitness before you move into bigger things. Great for all the family to enjoy with bike shop cafe etc.
If your looking for hardcore full face action then best head into the unmarked routes where you will not run the risk of hurting a less experirenced rider.
What could be improved?
None as long as you stick to the rules and you respect all other riders your be fine.
