Castle Peak is a prominent 8,343-foot (2,543-metre) mountain summit located in the Hozameen Range of the North Cascades, on the shared border between Okanogan County and Whatcom County of Washington state. The mountain is situated one mile (1.6 km) south of the Canada–United States border, on the Cascade crest, in the Pasayten Wilderness, on land managed by the Okanogan–Wenatchee National Forest. The nearest higher peak is Jack Mountain, 14.8 miles (23.8 km) to the south-southwest. Castle Peak is the second highest summit of the Hozameen Range following Jack Mountain. Castle Peak is the sixth-highest mountain in the Pasayten Wilderness. Precipitation runoff from the mountain drains east into Castle Creek, a tributary of the Similkameen River, or west into tributaries of the Skagit River. Topographic relief is significant as the summit rises nearly 3,000 feet (914 meters) above Crow Creek in 0.75 mile (1.2 km).
