The closest ski area to the Denver metro area, Echo Mountain is a front range ski resort that opened as a terrain park-only mountain in 2006. After several eras of ski ideology and different owners, Echo is now has something to offer for skiers of all kinds on about 60 acres of skiable terrain, with speakers wired all around for mountain-wide music, and fully lit runs for night skiing.
