Backpacking may include wilderness adventures, local travel and travel to nearby countries while working from the country in which they are based.
The definition of a backpacker has evolved as travelers from different cultures and regions participate in the trend.
However, the perception of backpackers seems to have improved as backpacking has become more mainstream.
Another criticism is that even though one of the primary aims of backpacking is to seek the "authentic," the majority of backpackers spend most of their time interacting with other backpackers, and interactions with locals are of "secondary importance." Planning and research can be an important part of backpacking, aided by such guides from companies like Lonely Planet and Rough Guides, books by travel authors such as Rick Steves, and various digital and online resources such as Wikivoyage.
The tilde, dot, comma, titlo, apostrophe, bar, and colon are sometimes diacritical marks, but also have other uses.
Backpacking in Europe, South America, Central America, Australia and New Zealand has also become more popular and there are several well-trodden routes around the world that backpackers tend to stick to.
Examples are the diaereses in the borrowed French words naïve and Noël, which show that the vowel with the diaeresis mark is pronounced separately from the preceding vowel; the acute and grave accents, which can indicate that a final vowel is to be pronounced, as in saké and poetic breathèd; and the cedilla under the "c" in the borrowed French word façade, which shows it is pronounced .
In Gaelic type, a dot over a consonant indicates lenition of the consonant in question.
Backpacking is a form of low-cost, independent travel.
It includes the use of a backpack that is easily carried for long distances or long periods of time; the use of public transport; inexpensive lodging such as youth hostels; often a longer duration of the trip when compared with conventional vacations; and typically an interest in meeting locals as well as seeing sights.
