Robert Louis Stevenson Museum

Honeymoons in Napa Valley are often epic – but as this museum records, the 1880 honeymoon of Robert Louis Stevenson and Fanny Osbourne was epically awful. Robert was sick and they were broke, so they wound up squatting in an abandoned bunkhouse at Mt St Helena's Silverado Mine (check out the museum's dollhouse-sized bunkhouse). But that honeymoon inspired Robert's novel Silverado Squatters, making his reputation for harrowing adventure stories – eventually including Treasure Island and Dr Jekyll and Mr Hyde.
