"Easy access makes this outing perfect for an after work or long lunch hour hike. This is the shorter of two Green Mountains in Jefferson County and the first named foothill as you leave Denver, going west. It provides the closest mountain view of Denver. Green Mountain is one of the excellent recreational areas of the City of Lakewood, a unique blend of the prairie and the Rocky Mountains in an urban setting. Its easy accessibility makes it a possible outing after work or over a long lunch hour.
This, one of several trailheads for Green Mountain, has the best parking area and the shortest distance to the top. While Green Mountain appears as a fairly non-descript, nearly treeless, rounded hill, it has some interesting geology. Green Mountain conglomerate—essentially a pile of gravel—makes up the mesa. This gravel was laid down as the adjacent Rockies rose and began to erode. Later, the valley to the west, which today contains C-470, eroded away to isolate the more resistant mesa from the foothills. This hike can be enjoyed nearly year-round, except right after a snow storm. The best time is perhaps late May, when a profusion of prairie wildflowers blooms on Green Mountains gentle slopes."
