A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. Unlike gas balloons, the envelope does not have to be sealed at the bottom, since the air near the bottom of the envelope is at the same pressure as the surrounding air.

In modern sport balloons the envelope is generally made from nylon fabric and the inlet of the balloon (closest to the burner flame) is made from a fire resistant material such as Nomex. Modern balloons have been made in all kinds of shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial, and many commercial, applications.

A safari is an overland journey, usually a trip by tourists in Africa. In the past, the trip was often a big-game hunt, but today, safaris are often to observe and photograph wildlife—or hiking and sightseeing, as well.

In 1836 William Cornwallis Harris led an expedition purely to observe and record wildlife and landscapes by the expedition’s members. Harris established the safari style of journey, starting with a not too strenuous rising at first light, an energetic day walking, an afternoon rest then concluding with a formal dinner and telling stories in the evening over drinks and tobacco. The hunting aspect traditionally associated with the safari is said to have its origins in the early 1800s in the region of Évora, Alentejo, where villagers got together to hunt wild boar and reclaim land for farming.

Mountaineering is the sport of mountain climbing. While some scholars identify mountaineering-related activities as climbing (rock and ice) and trekking up mountains, others are also adding backpacking, hiking, skiing, via ferrata and wilderness activities, and still others state that mountaineering activities also include indoor climbing, sport climbing and bouldering.However, to most of the scholars, the term mountaineering is understood as climbing (which now refers to adventure climbing or sports climbing) and trekking (hill walking in ‘exotic’ places).Hiking in the mountains can also be a simple form of mountaineering when it involves scrambling, or short stretches of the more basic grades of rock climbing, as well as crossing glaciers.

While mountaineering began as attempts to reach the highest point of unclimbed big mountains, the sport has branched into specializations that address different aspects of the mountain and consists of three areas: rock-craft, snow-craft, and skiing, depending on whether the route chosen is over rock, snow or ice. All require experience, athletic ability, and technical knowledge to maintain safety.

Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the traveller’s country. The World Tourism Organization defines tourism more generally, in terms which go “beyond the common perception of tourism as being limited to holiday activity only”, as people “traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes”.

These are other trips.
