The combination of accessible recreation amenities and natural beauty makes Otter Lake a valued destination in the Southern Interior.

The park supports wildlife typical of interior British Columbia's dry forests and lake ecosystems. Mule deer and black bears utilize the forested areas, while smaller mammals including beavers, muskrats, chipmunks, and ground squirrels are common around the lake and in the uplands. Birdlife includes waterfowl such as loons, grebes, mergansers, and various duck species on the lake, while osprey and bald eagles fish from prominent perches. Forest species including pileated woodpeckers, chickadees, nuthatches, and various warblers inhabit the surrounding woodlands. The lake supports fish populations including rainbow trout and potentially other species that attract anglers. Amphibians including frogs breed in the lake and wetland margins. Garter snakes may be observed basking on sunny rocks or trails. The lake and surrounding habitats provide important resources for wildlife in the dry interior environment.

Otter Lake Provincial Park features interior dry forest vegetation dominated by ponderosa pine and Douglas-fir, with lodgepole pine in some areas. The understory includes shrubs such as kinnikinnick, Oregon grape, soopolallie, and various berry-producing species. Grassland openings feature bunchgrasses and wildflowers including balsamroot, lupine, and various native species that create spring and early summer displays. Lakefront riparian areas support distinctive vegetation including black cottonwood, trembling aspen, willows, red-osier dogwood, and moisture-loving herbaceous plants that contrast with the drier upland forests. Aquatic vegetation may include water lilies and submerged plants in shallow lake areas. The relatively dry climate and ponderosa pine forests are characteristic of the transition zone between wet coastal forests and very dry interior grasslands. Fire has historically influenced forest structure and composition, maintaining open pine forests.

The park is situated in the Interior Plateau region where Otter Lake occupies a valley or depression likely influenced by glacial processes. The surrounding terrain consists of bedrock formations that may include volcanic rocks, sedimentary formations, or intrusive rocks depending on the specific geological setting. Glaciation during the Pleistocene epoch modified the landscape, with ice sheets depositing till and shaping valley configurations. The lake basin may have been deepened by glacial erosion or formed behind glacial deposits that impounded drainage. Soils in the park vary from coarse, well-drained mineral soils supporting ponderosa pine forests to finer alluvial and organic soils in lakefront areas. The lake's relatively warm summer temperatures result partly from its shallow to moderate depth allowing solar heating. The surrounding topography of gentle slopes and plateau surfaces reflects both underlying geological structure and glacial modification.

The park experiences an interior climate with cold winters and warm, dry summers characteristic of the Southern Interior of British Columbia. Winter temperatures typically range from -10 to 0 degrees Celsius with moderate snowfall, while summer temperatures average 15 to 28 degrees Celsius with warm, dry conditions ideal for lake recreation. Annual precipitation is moderate, generally 400-600 millimeters, with most falling during spring and fall. Summer drought is common, creating dry conditions and elevated wildfire risk. The lake typically freezes during winter and becomes ice-free in spring, with summer water temperatures warming sufficiently for comfortable swimming by late June or July. Spring brings wildflower blooms following winter moisture, while autumn features cooler temperatures and changing foliage colors. The relatively dry climate and warm summer temperatures make the park popular for camping and water recreation.

The region is part of the traditional territory of the Nlaka'pamux and potentially other interior First Nations who utilized lakes, forests, and valleys for fishing, hunting, and gathering. Lakes like Otter Lake provided important resources including fish and waterfowl. European settlement brought ranching, logging, and mining to the interior during the 19th and 20th centuries. The area around Tulameen saw gold mining activity and resource development. Small communities developed around resource extraction and ranching activities. Recreational use of lakes in the interior grew during the 20th century as road access improved and residents sought outdoor recreation opportunities. The establishment of provincial parks including Otter Lake provided public access to recreation resources while protecting lake and forest ecosystems from development. The park serves both local communities and visitors to the Southern Interior region.

Otter Lake Provincial Park was established to protect the lake and provide public recreation opportunities including camping, swimming, boating, and fishing. The park designation ensured public access while preventing lakefront development that could exclude public use. BC Parks manages the site to balance recreation with conservation, providing developed facilities while protecting water quality and natural ecosystems. The park has become a popular destination for families seeking accessible lake recreation in the interior. Management addresses challenges including high summer use, campground impacts, protection of shoreline vegetation, wildfire risk, and water safety. The park contributes to recreation opportunities in the Southern Interior and demonstrates sustainable management of popular recreation lakes balancing public access with environmental protection.

The park's main attractions are swimming at the designated beach areas with warm lake water during summer months, and camping in the developed campground allowing overnight stays near the lake. Boating including kayaking, canoeing, and small motorboats (where permitted) provide opportunities to explore the lake. Fishing for rainbow trout attracts anglers, with regulations requiring licenses and adherence to catch limits. The day-use area offers picnicking with views of the lake and mountains. Short walking trails allow exploration of the lakefront and surrounding forests. Wildlife observation includes watching for waterfowl, osprey, eagles, and potentially deer or bears. The park's playground and beach facilities appeal to families with children. The warm summer climate and lake recreation make it a valued destination during the camping season. Fall visits offer cooler weather and reduced crowds for those seeking quieter experiences.

The park offers a developed campground with vehicle-accessible sites, some with electrical hookups, along with washrooms, showers, water taps, and a sanidump station. Day-use areas feature parking, picnic tables, beach access, and potentially boat launch facilities. The park operates seasonally with full services typically from late spring through early fall, though some areas may be accessible year-round. Reservations are strongly recommended for camping during summer months due to high demand. The park is located near Tulameen, accessible via Highway 5A or local roads from Princeton and other Southern Interior communities.
