Licenses can be purchased online through the WDFW Licensing System or at authorized vendors.​

• Check Tides: Plan your trip during low tide for optimal harvesting conditions.

• Bring the Right Gear: A small shovel, bucket, and gloves can make your experience more enjoyable.

• Know the Limits: Familiarize yourself with daily limits and size requirements for each species.
