HistoryA character grade: shown, never part of Bonny Doon’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Bonny Doon’s 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C. The pre-1940 share is a Census survey estimate (±4.0 points). The founding year is the first post office, not a stated founding date.

What stands out about Bonny Doon’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
It was founded in the 1850s as a logging camp. The current name can be attested back to 1902: John Burns, a Scotsman living in Santa Cruz, named Bonny Doon after a line in the Robert Burns song "The Banks O' Doon". The line is: "Ye banks and braes o' bonnie Doon...", and refers back to the Doon River in Scotland. Evidence of 2,600 years of occupation by Native Americans has been found in the area.
Bonny Doon has no city center or commercial shops, but features several wineries including Bonny Doon Vineyard, a church, two fire stations, a lavender farm, the Bonny Doon Ecological Reserve, an elementary school, and a private-use airport. A beach of the same name is nearby.
