Additional Information

  • Most of the activities at Kopachuck center around the beach. During low tide, the sun warms the sand, which in turn warms the water brought in by the tide. The sandy beach is ideal for wading, sand-castle building and exploring the marine habitat.
  • The most popular day-use area is the beach. Getting there requires a short 1/8-mile walk down a hill. People with limited mobility may drive or be driven to the beach. Contact park staff to make such transportation arrangements.
  • A recreational license is required for fishing and shellfish harvesting at Washington state parks. For regulations, fishing season information, or to purchase a recreational license, visit the Washington Department of Fish and Wildlife.
