51Index Score / 100
#19 of 58 in California

Trinity County scores 51/100 on the Bolthole Index, a solid county profile. Its strengths are deep seclusion — about 1 people within a 30-minute drive and manageable long-term carry cost. The trade-offs: elevated mid-century heat, water, rain, or wildfire exposure and more administrative friction around building and land use.
