Each map is on a right-hand page in landscape format and depicts physical features in black and contour lines in red.

Each numbered map is accompanied by a description on the facing left-hand page, in which Strachey describes the portion of the route indicated, often justifying her topographical decisions with quotes from the book.

Christopher Tolkien refers to Journeys of Frodo a number of times in The History of The Lord of the Rings, often agreeing with Strachey's conclusions, and sometimes disagreeing.

Nancy-Lou Patterson, reviewing the work in Mythlore, calls it a "delightful contribution" to the understanding of The Lord of the Rings, agreeing with Strachey's comment that when she first read the novel, she wished she had had "a complete set of maps covering the journeys of Frodo and his companions".

Patterson writes that Strachey's maps "with their charming directness and laconic simplicity, come very close to the spirit of Tolkien's own line drawings, and form a genuine visual parallel to his novels".
