The Hama Hama Company is a family-owned shellfish farm located where the nearly unbearably scenic Hamma Hamma River meets Hood Canal (photos and a guide to life on the farm are over here). The Hama Hama Oyster Rama is a party on the beach with steamed clams, crab cakes, paella, and oysters galore. Also, a tideflat tour (educational but actually fun), the Shuckathalon (!), and live music all day long. Also-also, it benefits the Hood Canal Education Foundation and other area charities.
Directions to the Oysterama are over here—there's the Beautiful Route: 2.5 hours, and the Fast Route: 2 hours.
It is FUN. See you at the Rama!
