I just got back from Hood and I must say that Windell's does have the sickest park.
If you are going to go, make sure you go early on. The snow melts quick and lots of rocks are exposed.
But personally, I went to Camp of Champs last year. And I would reccomend it to anyone.
Windell's park is a bit better, but if you are looking for the overall best experience, you gotta go to Whistler.
COC has great coaches, great terrain, great town, freedom (you can do whatever you want. it's not so much a camp as it is a resort.), nightlife, and alot more.
If you want to have an awesome summer experience go to Camp of Champions,
If you just care about the camp with the most jumps then go to Windell's.
Bot are good, as well as High North.
Eat. Sleep. Breathe. Ski.
