Bybee-Nims Blueberry Farm is at the base of Mt. Si along the Middle Fork of the Snoqualmie River. They have acres of different kinds of blueberry bushes that were all brimming with huge, plump, tasty berries the day we were there in late July.
Picking blueberries is far easier than picking just about any other kind of berry. You're not bent over like strawberries and there are no thorns like blackberries. Just grab a cluster of berries and pull it toward you. The berries roll off into your hand.
We had trouble getting the berries into the bucket and not our mouths, but after only an hour we had almost 10 pounds of the best blueberries ever.
Good luck finding berries this good in a grocery store or for about a buck a pound!
