    CharacterReef dive

    Greys Harbor in the Pacific Northwest is primarily a shore diving destination, offering a relaxed approach to cold water diving. The main draw here is the chance to spot various crab species scuttling across the silty bottom, alongside small rockfish tucked into crevices. It’s a good spot for newer divers looking to get comfortable with their drysuits and gear in generally calm conditions, or for those just wanting a casual underwater ramble. Visibility can vary quite a bit, but on a good day, you’ll get decent views of the local critters.

    Safety Notes

    Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
