Chopaka Mountain is a high mountain peak at an elevation of 1.903m (6,243ft) above the sea level, located in Okanogan County, in the U.S. state of Washington along the Canada–US border. It’s one of the highest mountain roads of Washington.
The road to the summit, located the North Cascades, is gravel, rocky, tippy and bumpy at times. It’s called Ninemile Creek Road. The road is usually impassable from October to June (weather permitting). Expect a trail pretty steep. Although most of the road is gravel, it’s doable by most street-legal vehicles. Thunderstorm activity can quickly change unpaved roads to four-wheel-drive condition or make them impassable. At the summit, part of the Chopaka Mountain Natural Area Preserve, there’s a parking lot of the Cold Springs Trailhead.
