I can't really say I have any guilty pleasures if simply because I don't possess enough of a sense of shame to feel guilt over any of them.
Travel writing is a mood that strikes me every once in a while but I must admit I prefer the earnest over the ironic, which unfortunately seems to be the dominant style these days. While I loved Bill Bryson's
A Short History of Nearly Everything, I haven't much cared for his actual travel writing.
Three books that I did enjoy were
Canyon Solitute: A Woman's Solo River Journey Through the Grand Canyon by Patricia C. McCairen and
Femme D'Adventure: Travel Tales from Inner Montana and Outer Mongolia by Jessica Maxwell. The obvious common theme in the titles is mostly coincidental.
In the more ironic format I did enjoy
The Sex Lives of Cannibals: Adrift in the Equatorial Pacific by J. Maarten Troost.
