Located less than 90 miles from Seattle, Washington’s sprawling North Cascades National Park Service Complex is a treasure trove of ecological diversity and a rugged wilderness playground for sightseers, hikers, climbers, and boaters.
Total acreage of North Cascades National Park (504,781 acres), Ross Lake National Recreation Area (117,575 acres) and Lake Chelan National Recreation Area (61,947 acres). These three separately designated (but contiguous) NPS units are administered as a single entity called the North Cascades National Park Service Complex.
Acreage of the Stephen Mather Wilderness Area (designated Nov. 16, 1988), which includes about 93% of North Cascades National Park and portions of the adjoining Lake Chelan and Ross Lake National Recreation Areas. There are also five federally designated wilderness areas in three adjoining national forests (Mount Baker-Snoqualmie, Okanogan, and Wenatchee). The North Cascades National Park Service Complex forms the core of more than two million acres of federally designated wilderness, one of the largest such areas in the 48-state U.S. Three Canadian provincial parks to the north (Chilliwack Lake, Skagit Valley, and Manning) preserve additional large tracts of wilderness.
Recreational visitors in 2009, including 288,458 at Ross Lake NRA and 34,554 at Lake Chelan NRA. The tally at North Cascades National Park was just 26, 972. Among the National Park-designated NPS units, only Michigan's Isle Royale National Park gets fewer visitors.
Acres of old-growth forest. The ancient forests of the North Cascades are remarkably lush. In fact, they have as much biomass per square mile as any place on earth.
More than 9,000
Feet of vertical relief. The steepness and heavily glaciated character of this mountainous terrain makes it a favorite with climbers and alpine trekkers.
At least 1,630
Vascular plant species documented in the eight distinctive life zones of North Cascades National Park. The great variations in rock and soil types, exposure, slope, elevation, and precipitation make the North Cascades one of the most ecologically diverse places on earth.
Miles of trails. North Cascades is a hiker’s smorgasbord, offering trails ranging from short and easy to long, steep, and grueling.
Documented glaciers, most of which are melting and retreating due to climate warming. About half of the glaciers in the 48-state U.S. are in the North Cascades Range.
Documented prehistoric sites, some 8,500 or more years old. There are also 81 significant historic sites, including homesteads, sawmills, mines and mining camps, sheep herder camps, fire lookouts, and even a “lost” hotel.
Number of natural alpine lakes. Waterfalls are abundant too (and in fact, inspired the name North Cascades).
Backcountry campsites available by permit. Demand is light in most areas, but permits for popular cross-country zones and climbing areas tend to go quickly. The odds improve when visitors keep group size small, visit midweek, and arrive early at the ranger station.
Designated backcountry camps within trail corridors, where camping is allowed only in designated sites. (No cross-country camping is allowed within one-half mile of a trail or one mile of a designated camp) Each designated site in the trail corridors has a flat tent pad area, pit or composting toilet, and access to water. Designated camps at lower elevations also have fire rings.
Switchbacks on the 7.5-mile long Purple Trail.
Minimum length (feet) of the light line each camping group must bring so as to be prepared for hanging food, etc. at least 15 feet up and 5 feet out from the trunk of a tree. Regulations call for using wildlife-resistant food storage lockers or canisters (“bear cans”) where appropriate and available.
Miles of paved road. Gravel roads are the standard in the North Cascades National Park Service Complex.
12 or 6
Maximum party size for backcountry use. Since the backcountry camps in the cross-country zones and climbing areas vary in capacity, the party size limits (which are strictly enforced) vary by area/zone. The limit in certain high-use areas is 12 pairs of eyes (including horses, mules, donkeys, and llamas), but for most other areas it is just six. Oversize groups are required to divide into smaller groups that remain spaced at least a half-day’s travel apart and stay at different backcountry camps.
Miles of road (all unpaved) inside North Cascades National Park. One of these roads starts in Stehekin, a community so remote that it has to be reached by boat or floatplane. The other is the Cascade River Road, which takes about an hour to drive and leads only to trailheads for fairly steep trails.
Research Natural Areas, including Silver Lake, Pyramid Lake, Boston Glacier, Stetattle Creek and Big Beaver Valley. Research Natural Areas are pristine areas that typify certain habitat types or environments having unique characteristics of scientific interest.
Number of times since 1976-77 that State Road 20, the only the only road that traverses the park from east to west, has remained open the entire winter. During a typical winter, heavy snow and frequent avalanches bury the highway beyond Ross Lake Trailhead from mid-November to April.
Entrance fee. No component of the North Cascades National Park Service Complex charges an entrance fee.
