The activities enjoyed in the Kilby Provincial Park include fishing (cutthroat and rainbow trout), water skiing, boating, swimming, camping, picnicking and birdwatching.
The small provincial park measures 3 hectares and falls within the boundaries of the Coastal Western Hemlock biogeoclimatic zone. The low-lying river valley environment is part of the Fraser Valley floodplain region and therefore it is home to forests consisting of cottonwood, alder, poplar and willow trees.
The park is identified as a British Columbia Wildlife Watch area. The river are resting and feeding grounds for migratory and resident birding wildlife. During winter months the area is a migrating stop for Bald Eagles and Trumpeter Swans arriving from Alaska.
The provincial park includes a drive in campground, a day use picnic area, a sandy beach area, swimming area and a boat launch. The day use area is located near the beach and includes picnic tables and pit toilets.
Near the entrance to the park is the General Store Museum. It was once the home to Thomas Kilby who came to the area in 1902 and opened a hotel and general store. Today it operates as a museum with artifacts and historical photos.
