Echo Mountain was originally opened from 1960-1975 as Squaw Pass Ski Area and was a Denver family favorite as it was much closer to the front range than areas further into the mountains. When the Eisenhower Tunnel opened in 1973 ski areas on the west side of the Continental divide began to expand.

After closing in 1975, it changed ownership a couple of times and laid dormant until 2005 when it was resurrected as Echo Mountain Park with a sole focus on terrain parks.
