"This park is mostly wide, super-groomed trails and a good chunk of service road. There's a total of about 17 miles of trail open to MTBs. You can do it all without repeating yourself much. The full meal deal will have you hitting about 3K verts at altitude, so it's more than just a ride in the park. This is a great exercise/training ride, with some great scenery. But it's really a lot like doing nearby Buffalo Creek with all the climbing but not all the fun. Park is hugely busy on weekends, I recommend doing the Marmot Passage trail clockwise for a more doable climb followed by hitting the best techy bits in the park on the descent. I also recommend doing the Borderline/Mason Creek Trail combo clockwise. The climb up borderline is quite heinous, but this is the only way to bet the longest fast and flowy downhill in the park. Of course, if you prefer a long, gradual climb with a shorter, steeper descent, reverse this portion." -skibum
