Cougar's housing stock is small in scale and closely tied to its recreation setting. Homes include modest cabins, forest-edge cottages, and a scattering of larger properties on wooded lots, with many situated for easy access to Yale Lake, Swift Reservoir, and the surrounding national forest. The limited development reflects the community's unincorporated status and its location within a largely forested landscape, so buyers should expect low density, private well and septic systems common to rural areas, and a mix of primary residences and seasonal or vacation properties. The market character is decidedly rural and recreation-oriented rather than suburban, with few large tracts of subdivision housing.

Cougar is too small to be divided into formal neighborhoods, and its layout follows the geography of the Lewis River valley. The community's small commercial core sits along State Route 503, with residences clustered near the highway and along the northwest shore of Yale Lake. Beyond the center, homes are dispersed through the forested foothills, accessed by secondary roads and forest routes that lead toward Mount St. Helens and the national forest. This spread-out pattern means neighbors are often separated by woods rather than by streets, giving the whole community a secluded, forest-bound character rather than a conventional in-town feel.

Life in Cougar is defined by the outdoors. As the closest community to Mount St. Helens, the town functions as a base camp for hikers, anglers, boaters, campers, and forest visitors, with a quiet, low-key rhythm shaped by the surrounding national forest and the Lewis River reservoirs. The year-round population is small, while seasonal visitors swell the community during warmer months. Local establishments such as resorts, campgrounds, and small businesses serve both residents and travelers. The lifestyle here favors self-sufficiency, open space, and ready access to wilderness, appealing to those who want to live at the edge of the Cascades rather than in a conventional suburban setting.

Students in the Cougar area are served by the Woodland School District, a K-12 district headquartered in the city of Woodland to the southwest. The district serves a corridor of communities along the Lewis River and the Interstate 5 area of northern Clark and southern Cowlitz counties. For families in Cougar, this means a commute to schools in and around Woodland, reflecting the community's rural, low-population setting where no local campus operates within the immediate area. The district provides the full span of elementary, middle, and high school education, and its schools serve as the educational anchor for the wider Lewis River valley region.

Cougar is reached primarily by Washington State Route 503, which runs north from Woodland and Interstate 5 into the Lewis River valley and the Mount St. Helens area. The community sits about 28 miles northeast of Woodland and roughly 50 miles northeast of Vancouver, making the I-5 corridor the principal route for longer-distance travel to the Portland-Vancouver metropolitan region. Within the area, forest roads and secondary routes branch off State Route 503 toward the national forest, the reservoirs, and Mount St. Helens. Personal vehicles are essential, and the highway connection is central to both daily life and the community's role as a recreation gateway.

Recreation is the defining feature of life around Cougar. The community gives access to the Gifford Pinchot National Forest, with its extensive trail system for hiking and mountain biking, as well as waterfalls, campgrounds, and forest roads leading toward Mount St. Helens. Yale Lake, Swift Reservoir, and Lake Merwin provide boating, kayaking, and fishing on the Lewis River system, and Cougar Park offers a lakeside campground and boat launch. Mount St. Helens itself, with the surrounding National Volcanic Monument, draws visitors for climbing, viewpoints, and interpretive sites. Snow sports, hunting, and dispersed camping round out a recreation calendar that runs through all four seasons.
