Whistler BC
River runs through it - technical flat starts slow ends hard. Manmad obstacles
Forplay - Living hell. Double diamond uphill. I don't know anyone who can ride the whole thing. Diamond back down. total ride 3 hours.
Emeral Forest - low to mid level normal non technical non manmade.
Mels Dilema - Intermediate to advanced. Good overall trail nothing manmade that I have seen. (new trail to me)
Flank - xc - long - steep frist climb rewards with several branching off dh's (including into mels dilema)
Thats it really.
