there is only 1 'official' climb (well 2, ST and fire road, they are parallel), it's OK as long as you are not on a 'sled' (or 'rig') and used to riding a bit, I didn't mind the climb at all.
bear in mind also you're not obliged to do top to bottom every run, you could session the bottom 1/3 for instance which has lots of interesting bits
on the flip side the average descent gradient is steeper (and faster) than a typical trail centre so you would proportionally spend more time climbing out of the total. I used it as chill out time.
lots of threads on this already, search is your friend
