Any visitors will find that the small enclave of Collinsville, California, is not much remarkable beyond the beautiful landscapes and waterside view. The town is an unincorporated community in Solano County, at the mouth of the Sacramento River. Visiting there felt intrusive. I drove past one or two “do not pass” signs, so I would not recommend you to visit. There is not much to see, anyway. The town endured significant damage from a wildfire on July 4th, 2014.
