Switzerland Trail is a very scenic journey in Boulder County, Colorado, United States. This trail had lots of twists and turns, bumps and wonderful sites to see. It’s an old railroad grade that zigzags across the mountains of Boulder County.
The trail (National Forest System Road 327) is rough and rocky. The grades are moderate. Thunderstorm activity can quickly change unpaved roads to four-wheel-drive condition or make them impassable. Much of this road is high clearance two-wheel drive, but it is one lane in places (typically 8–10 ft (2.4–3.0 m) wide) on a shelf with little to no room to pass another vehicle.
Best time to drive the trail is May through December; some segments may be blocked by snow in winter. The trail offers some wonderful views. Caution should be exercised if snow or wet conditions are present. Its highest elevation is 9,179 feet (2.797m). The trail follows the remains of a narrow gauge railroad, called the Switzerland Trail for its scenic beauty, that operated from 1883 to 1919. The drive is 14.0 miles long.
