In northeastern Washington, only 25 miles from the U.S.- Canada border, the park is named for 5.5-mile-long Curlew Lake, an angler's dream. A fisher's catch might include trout, bass, yellow perch or tiger muskie. Bald eagles, ospreys and herons also like the fishing at Curlew; they live in the neighboring trees and can be seen flying in to pluck a meal from the lake. A heron rookery with active nests is visible from the park.
Water sports activities abound in summer, and snow sports are popular in winter. The green lawns are tailor-made for play, and the campground, with many lakeside campsites, is said to be one of the most restful in Washington.
