I have a weakness for travel books of the early 20th century - when the world was full of countries with lots of wild and weird experiences to be had. A quick look through my stash turned up these adventures:
Brazilian Adventure by Peter Fleming - “Fleming and his companion set off for Amazonia to determine what happened to an explorer who’s disappeared seven years before searching for a lost city of gold. They didn’t find him and, as Fleming admits, didn’t face death or hordes of cannibals. Instead, they had a rollicking, sometimes trying adventure in the midst of a Civil War. with their greatest adversary their alleged guide. Fleming was the brother of James Bond creator Ian Fleming. Ian supposedly idolized his brother. With good reason.”
Hindoo Holiday by J.K. Ackerley - “Ackerley recorded the Maharajah’s fantastically eccentric habits and riddling conversations, and the odd shambling day-to-day life of his court. Hindoo Holiday is an intimate and very funny account of an exceedingly strange place, and one of the masterpieces of twentieth-century travel literature.”
Far Away and Long Ago by W.H. Hudson - "Far Away and Long Ago is told with such passion and candor that the grassy plains of Argentina, the gauchos, the birds and wildlife emerge from the pages. Not only great natural history, Far Away and Long ago is one of the most magical childhood memoirs ever written. "
and a bit earlier:
Following the Equator, A Journey Around the World by Mark Twain - " brimming with Twain’s celebrated brand of ironic, tongue-in-cheek humor. Written just before the turn of the century, the book recounts a lecture tour in which he circumnavigated the globe via steamship, including stops at the Hawaiian Islands, Australia, Fiji Islands, New Zealand, India, South Africa and elsewhere."
The Twain is perhaps too long but more varied in locale.
