I know that there have been some posts from previous years, but wondering if anyone has any favorites?
Clayton Valley Pumpkin Farm in Clayton... it's way out in the hinterlands, but it's fun. They have the pumpkin patch, craft fair, play areas and a train ride thing. It's a popular school field trip this time of year.
I really like Spring Hill Farm in Petaluma. Nice patch and all sort of pumpkin goodies using milk from their Jersey cow. The pumpkin quark and pumpking Ice cream are tasty.
Here's a good article about North Bay pumpkin patches.
It is not a pumpkin patch, but Oak Hill Farm in Sonoma had the loveliest pumpkins with different varieties.
