A Wandervan Campervan is a great way to explore the area Bike Parks! There are some amazing parks out there and each one is unique offering a different experience. We only rank those parks that we have specifically ridden the lifts at recently. As we visit more bike parks we will added them into our ranking system. Our ranking system is based on the green to single black offerings at each bike park.
Big Sky has made some big changes lately and move away from just being the bike park with super gnarly DH runs. Off the Ram Charge Lift there are now some great flow trails that will put a grin on anyone's face. The gnarly DH trails are still available too, just be prepared for changing some flat tires. There is a great deal of sharp shale rock that tends to eat tires so be prepared with spare tubes and tires.
Sun Valley has made some huge changes recently and there are some actual lift served trails as opposed to just cross country trails. All of the trails on the mountain are targeted at riders with enduro style bikes, so leave your DH bike at home for your next visit. The two main bike park specific trails are Saddle-Up and Lupine. Both of them are fun for a couple of laps. Then be sure to hit up the old Warm Springs trail for some classic Sun Valley singletrack.
Brundage has come a long way since a couple of years ago. You still have the classic singletrack trail Elk Meadows and then the DH trail Hidden Valley. While both trails are fun it is very hard to progress from Elk Meadows to being able to ride Hidden Valley. The Growler trail which is intermediate was being work on a lot this summer so this should provide a better progression for 2017. Hidden Valley has some large mandatory air sections so be prepared.
