Montagu Pass is situated in the Western Cape province of South Africa, on the unsigned road between Herold and George.

The pass was named after John Montagu, Colonial Secretary of the Cape in the 1840s, whose enthusiasm for good roads resulted in the first ambitious program of construction in Southern Africa.

The passage over the Outeniqua mountains, which used to take a full three days over the Cradock Pass, could now be accomplished within three hours.

Henry Fancourt White, an English-born early emigrant to then Cape Colony, was an experienced road engineer in charge of the work.

Where the road passes underneath the railway bridge, is "Stinkhoutdraai" where stinkwood trees used to grow in profusion.
