Geocaching  is a treasure-hunting game that involves the internet, GPS map coordinates and travel. There are millions of geocaches worldwide. Geocaches are classified 1-5 for two kinds of difficulties, the terrain, and the hide. A 1/1 would be an easy hide on an easy (wheelchair accessible) terrain. A 5/5 would be a difficult hide on difficult terrain, ie: requires a boat or scuba gear. There are different kinds of geocaches: traditional, puzzles, virtuals (no cache, but answers to questions must be posted to the cache owner, events such as small meet and greets, CITOs, Earth Caches teach earth sciences, film festivals about geocaching, and mega and giga events where hundreds of geocachers gather. Players report their treasure hunt activities online to gain credits for their finds. Many of the players place caches (treasures) in spots they are quite fond of. So hunting them down will quite often lead to exciting adventures in lesser known locations, even in your local neighbourhood. The goal is to find the cache, write your username in the logbook, put the cache back where you found it, and log the find online. Caches must be placed 161 meters from each other but in many places there are geocache series of dozens to thousands of finds, along a trail or road.
One aspect of the game is to carry treasure(trackable) from one cache to the next or from one event to the next event. Trackables have identification information and a webpage, so their travels can be tracked online. To play the game you will need a GPS receiver (or a map and the orienteering skills to use it), the cache description (make a printout) and about 1 hour spare (more for a difficult cache). Modern phones also have geocaching apps, though a phone isn't as rugged as a dedicated GPS unit and can be useless when offline.
Related to geocaching is the Degree Confluence Project where people contribute photographs of the planet at points of intersection of lines of longitude and latitude. Most of the easy ones are done - but if you are heading way off the beaten track this may be for you.
Orienteering  is another popular outdoor sport. It involves using a map and terrain navigation skills to follow a course in the least time. The sport has an international following, world championships, and training programs, and takes place in beautiful and interesting locations. Orienteering meets hosted by the top clubs draw thousands of participants from around the world.
Main article: Golf.
Golf is a game that is variously considered a pastime, recreation, sport, profession, religion or an obsession. To some the game is more an opportunity for relaxation than sport, and many travelers roam the world looking for unique and famous golf courses on which to hone their skill.

Main article: Alpine skiing.
Alpine skiing, also known as downhill skiing, is a popular sport involving sliding down snow-covered terrain with skis attached to each foot. Ski resorts around the world attract millions of travelers yearly.
Snowkiting is "winter's newest extreme sport", requiring only the wind, a snowkite, skies or snowboard, and an attitude for fun. The sport has endless possibilities, such as backcountry skiing without a ski lift or resort - your snowkite will pull you uphill and downhill at varying speeds. Snowkites can accelerate up to 50 MPH. The lifting power of the wind will allow you to jump to distances of up to 100 feet.
When snowkiting in the backcountry be aware of avalanche danger! Always snowkite in groups, wear an avalanche beacon, dress warm, and never exceed your limits.
Main article: Agritourism.
Agritourism means travel organized around farming or animal husbandry. Visiting a working farm or ranch for the purpose of enjoyment and education are key parts of this often rural experience. Farmer's markets, wine tourism, cider houses and corn mazes all constitute examples of agritourism. Travelers who participate in this type of vacation frequently desire to see how food is grown and prepared or to learn how how animals are raised.
Birding or Birdwatching is an activity that is undertaken by both the hobbyist and the professional scientist.

"Food Tourism" is the pursuit and enjoyment of unique and memorable food and drink experiences, both far and near. Food travelers experience different cultures through the food and drink of that culture. Whether in a destination far away or a local neighborhood, food and drink are expressions of that culture, its heritage and tradition. Food and drink are tools for communication, and food tourism promotes the understanding and appreciation of different cultures as expressed through food and drink.
Hot air balloons
Motorcycle tours vary in discipline, group size and distances, according to style of tour, terrain ridden, motorcycle size and model, and activity classification (eg sport or pleasure).
Road Touring The mainstream activity, involves riding conventional roadgoing motorcycles, usually bigger displacement machines and can be done by solo adventurers as well as in groups with tour leaders.
Dirt Bike Touring Most dirt bike touring is done on a combination of sealed roads and off-road unsealed roads, tracks, trails and sometimes open countryside where the law permits. Bikes are usually of smaller displacement, and are generally lighter than roadgoing motorcycles, with more ground clearance too, to facilitate crossing rough terrain and hazards. Best done in groups, with a local guide, as getting lost in remote areas in a foreign land can lead to potentially life threatening situations.
Dual Sport Touring or Adventure Bike Touring or ADV Touring As for dirt bike touring, though touring is usually done on large displacement machines, and road to off-road distances tend to be considerably weighted towards paved or graded roads.
Enduro Touring As for dirt bike touring, though distances on paved highways are generally kept to minimum, and off-road routes and tracks and trails tend to require more technical riding ability. Usually longer hours are spent on the bike, and much rougher terrrain is ridden than in all other types of Motorcycle Touring.
Learning languages abroad
Travelling to a foreign country both for leisure purposes and to study the local language can be an excellent way to deepen ones experience in a foreign culture and to combine leisure with learning. Although perhaps more common for people between the ages of 18 and 24, language tourism is undertaken by people of all ages and backgrounds. They tend to enroll in non-intensive foreign language courses that allow considerable free time in which to practice the language outside of class and travel extensively. Typical stays range from 2 to 5 weeks, and trips are often repeated in subsequent years.

Riding quad bikes (also known as ATVs--all-terrain vehicles) is a sport that involves riding on a small, rugged vehicle, usually in off-road areas. This activity is provided by commercial operators around the world:
Riding independently, quad bikers should consider possible damage to soil and plants, and thus check local regulations prior to embarking on a trip.
Normally, quad bikes are designed only for a single rider (although are frequenly rented for riding by two). There's only one model of quad bike that has is designed for two persons, and that model is quite rare in commercial rent.
Main article: Scuba diving.
Scuba diving is a sport in which people breathing from tanks of compressed air explore underwater areas. It's most popular in areas with tropical coral reefs, but there are scuba diving sites in most areas of the world with water.

Main article: Wine tourism.
Wine tourism means organizing travel around the appreciation of, tasting of, and purchase of wine. It is a kind of tourism highly developed in many regions around the world, and it can be as simple as hopping on a wine shuttle in Napa Valley or as complicated as renting a villa in the south of France for a month. Wine tourism is a great way to learn about the people, culture, heritage, and customs of an area. Some of the famous wine producing regions of the world have been producing wine for centuries or even millennia, and the production and consumption of wine is deeply ingrained in the local culture.
Main article: Zip Lining.
Zip lining refers to an activity where participants (often referred to as “zippers”), are suspended from a pulley that moves across across a cable suspended between trees or man-made structures. The cables are mounted descending from a higher to lower point which propels the zipper purely by the use of gravity. The amount of incline as well as the weight of the zipper determines the speed at which the participant travels from point to point.
Zip line courses can be designed purely for speed (adrenaline rush), while others are designed to allow zippers to enjoy the natural surroundings such as forest, jungle or waterfalls (often referred to as canopy tours). While others employ elements of both.
