If you’re a self-identified park rat, you probably know Whistler’s park just opened for bikes. Here in Southern California, Whistler is quite a ways away. But we’re OK with that, because we have Mammoth and Snow Summit with more than enough trail to satiate any DH rider’s need. And they’re opening this Friday, May 25. More importantly, for the first time ever, one season pass will give you access to both resorts for a cool $350. Single day tickets at Snow Summit are also currently available at a 20-percent discount if you purchase a least 72 hours in advance.

Snow Summit will be 100-percent open this Friday. To celebrate there will be live music all weekend and vendors will be offering the opportunity to test new gear. For now, the park will only operate on weekends (Friday through Sunday) and holidays until June 18, when mid-week operation will begin.

Mammoth Bike Park won’t be opening the entire park immediately—the mountain did just announce the ski season would continue until June 17—but a handful of trails will be open for riding. The following 11 trails are snow-free and ready for sending this Friday: Downtown from F Stop, Gopher Trail, Big Ring, Paper Route, Timber Ridge, Lakes Trail, Juniper, Smooth Operator, Lower Bullet, Uptown and Shotgun. Work has also begun on a new advanced DH trail coined Boomerang with a planned opening the first weekend of July.

Mammoth will also be allowing full e-bike access in the park this year, and a full fleet of Trek e-bikes will be available for demo.

Break out your big rig, lube the chain, make sure the suspension is dialed, get in touch with your inner park rat and catch a chair this Friday.
