Pacific Rim National Park Reserve is a Canadian national park in British Columbia made up of three separate regions: Long Beach, the Broken Group Islands, and the West Coast Trail. The entire park encompasses 511 km² of land and ocean. The park is characterized by rugged coasts and lush temperate rainforests. The park is open from mid-March until mid-October. The park encompasses a thin strip of land located on the south-west coast of Vancouver Island. To the east of the park lies the Vancouver Island Ranges of the Insular Mountains and to the west is the Pacific Ocean. During fall and winter, the area is continually subjected to moist air masses from the Pacific Ocean. The presence of the mountain ranges causes the air masses to rise and deposit large quantities of precipitation, a phenomenon known as orographic precipitation. The area averages over 3000mm of precipitation per year, a key factor in producing temperate rainforests. During the drier summer months the area is frequently covered in fog. Average temperatures range from 14°C (57°F) during the summer and 6°C (43°F) in the winter.
