With summer adventures such as mountain biking, fly-fishing and rafting competing for your time, it’s never a dull moment at Keystone. Nearly sixty miles of trails - from scenic singletracks to screaming downhill runs - provide some of the best mountain biking in the country, and two award-winning golf courses wind along the Snake River and up through alpine meadows. Summer events include a beer and bluegrass festival, musical theatre productions, performances from a national repertory orchestra, a fishing derby and kids’ discovery days with crafts and entertainment.
