Jakob Burckhardt, in The Civilization of the Renaissance in Italy (in German in 1860) declared Petrarch "a truly modern man", because of the significance of nature for his "receptive spirit" even if he did not yet have the skill to describe nature.

However, some have suggested that Petrarch's climb was fictional. The exploit is described in a celebrated letter addressed to his friend and confessor, the monk Dionigi di Borgo San Sepolcro, composed some time after the fact. Petrarch recounts that on April 26, 1336, with his brother and two servants, he climbed to the top of Mont Ventoux (1,912 meters (6,273 ft), a feat which he undertook for recreation rather than necessity. The poet Petrarch is frequently mentioned as an early example of someone hiking. In North America, multi-day hikes, usually with camping, are referred to as backpacking. Hiking a long-distance trail from end-to-end is also referred to as trekking and as thru-hiking in some places.

Trekking is the preferred word used to describe multi-day hiking in the mountainous regions of India, Pakistan, Nepal, North America, South America, Iran, and the highlands of East Africa.

The Australian term bushwalking refers to both on and off-trail hiking. In extreme cases of bushwhacking, where the vegetation is so dense that human passage is impeded, a machete is used to clear a pathway. This specifically refers to difficult walking through dense forest, undergrowth, or bushes where forward progress requires pushing vegetation aside. Hiking sometimes involves bushwhacking and is sometimes referred to as such.
