Parking is very limited at the trailhead and fills up quickly on weekends. The trailhead is to the right of the blue truck in this picture.
Located west of Monument and south of Palmer Lake, Raspberry Mountain is a broad, wide peak next to Mt. Herman. It suffers an identity crisis, overshadowed by its more popular neighbor, Mt Herman, and sharing the exact same name of a peak near Divide in Teller County (thanks to whatever genius thought that was a good idea).
This hike is a four-, four-and-a-half-, or seven-mile hike roundtrip, depending on which landmark you turn around at. Raspberry Mountain's elevation and heavy tree cover makes it a nice hike on hot summer days, and the lower portions are ripe for really great wildflower viewing in early summer.
To get there: Take I-25 to the Monument exit. Take 2nd Street through downtown Monument, and make a left turn on Mitchell Road after crossing the railroad tracks on the west end of downtown. Take Mitchell Road to Mt. Herman Road and turn right. Take Mt Herman Road 7 miles or so to the trailhead which is a wide turnout on the right side of the road. The road is windy, narrow and rocky past Red Rocks Road, but with care, all but the lowest ground clearance cars can make it to the trailhead. The road is open all year, but is not maintained in winter.
