River climbing, river trekking, river tracing or mountain stream climbing is a form of hiking or outdooradventure activity, a traditional sport in Japan and popular in Hong Kong and Taiwan, and, in some ways, similar to canyoning or canyoneering. River trekking is a combination of trekking and climbing and sometimes swimming along the river.[1] It involves particular techniques like rock climbing, climbing on wet surfaces, understanding the geographical features of river and valleys, knotting, dealing with sudden bad weather and finding out possible exits from the river.
Japan and Taiwan are the most popular destinations for this sport.
The most famous 100 mountain streams to climb in Japan can be found by looking up 百名谷.
Taiwan
This sport is popular throughout Taiwan, where it is generally called river tracing (溯溪). The Hualien and Yilan areas are the most popular destinations for river tracing.
River tracing is a popular activity among the people of Taiwan. Accomplished river tracers may start from the mouth of a river. Several wilderness survival skills are needed, such as rock climbing, swimming and camping. However, there are different levels of difficulty, so beginners can take part. For beginners, it is advisable to choose an easier and more relaxed route, which can be completed in half a day. With safety equipment and an experienced coach, a participant can gradually master the skills needed to walk upstream. Sometimes it is necessary to swim through deep pools or climb up waterfalls. With a life vest, a non-swimmer can river trace as well.

Nine Big Rivers
The Nine Big Rivers (九大石澗) are the nine streams that are most popular among river trekkers in Hong Kong. The Nine Big Rivers include:
close to the border between Hong Kong and mainland China
Philippines
In the Philippines, river trekking is just gaining its popularity especially with the introduction of Mapawa Nature Park in Cagayan de Oro in Mindanao on one of their must-do activities. There are five challenges in the river which includes swimming, rappelling, jumping and sliding among others.
The particular nature park was featured on GMA 7's now defunct reality show Extra Challenge.
South Africa
The South African version of river trekking is called kloofing and has gained a similar following from both an informal recreational and commercial point of view.
Rating of difficulties
As river trekking has a certain level of risk, experienced river trekkers or hiking groups have developed rating systems about difficulties on different rivers. The ratings usually are various from 1 to 5 stars, even though a few rivers can be more than five stars because of their extreme difficulties. Such ratings are largely subjective, depending largely on river trekker's own experience. Therefore, different people or hiking groups would give different number of stars on the same river. According to Hong Kong Adventurer, an English Website about hiking and river trekking in Hong Kong, difficult scale of different rivers as:[2]
Number of stars
Description
1
can be handled by normal healthy persons
2
not too easy
3
fairly difficult
4
difficult, absolutely not for beginners
5
very difficult, very demanding in term of strength and skill
River trekking has a certain level of risk. There are occasional accidents in river trekking, including falls from steep cliffs or waterfalls, drownings, exhaustion, or getting lost. Risks that should be prepared for include the following:
Flash flooding poses a serious danger. Sudden changes in weather, like rainstorms, can cause rapid rises in the level and speed of the river water. Also, the number of viable paths and climbing areas inside the river valley could be reduced suddenly in a very short period.
Visibility can be limited by rainy or misty weather. Low visibility may come in too quickly for trekkers to adapt to. Therefore, a torch (flashlight), preferably a head-mounted one, is a must for river trekking.
Steep cliffs inside river valleys require a certain level of rock-climbing skills. However, because of the humid environment inside river valleys, some rock surfaces can be wet and some rocks may be loose despite appearing solid. To deal with wet climbing conditions, professional river-trekking boots are strongly advised.
Bouldering is a form of free climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses. While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls. Unlike free solo climbing, which is also performed without ropes, bouldering problems are usually less than six metres (20 ft) tall. Traverses, which are a form of boulder problem, require the climber to climb horizontally from one end to another. Artificial climbing walls allow boulderers to climb indoors in areas without natural boulders. In addition, bouldering competitions take place in both indoor and outdoor settings.
Half Dome is a quartz monzonite batholith at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. It stands at nearly 8,800 feet above sea level and is composed of quartz monzonite, an igneous rock that solidified several thousand feet within the Earth. At its core are the remains of a magma chamber that cooled slowly and crystallized beneath the Earth's surface. The solidified magma chamber was then exposed and cut in half by erosion, therefore leading to the geographic name Half Dome.
Many climbing routes have a grade that reflects the technical difficulty – and in some cases the risks and commitment level – of the route. The first ascensionist can suggest a grade, but it will be amended to reflect the "consensus" view of subsequent ascents. While every country with a strong tradition of climbing developed its own grading systems, a small number of grading systems have become internationally dominant for each type of climbing, which has contributed to the standardization of grades worldwide.
Hiking is a long, vigorous walk, usually on trails or footpaths in the countryside. Walking for pleasure developed in Europe during the eighteenth century. Religious pilgrimages have existed much longer but they involve walking long distances for a spiritual purpose associated with specific religions.
Scrambling is a mountaineering term for ascending steep terrain using one's hands to assist in holds and balance. It is also used to describe terrain that falls between hiking and rock climbing.
Canyoning is a unique sport that combines several outdoor sports like rock climbing, hiking, swimming, and rappelling. A canyoneer travels down canyons using a variety of techniques that may include other outdoor activities such as walking, scrambling, climbing, jumping, abseiling (rappelling), and swimming.
Rock climbing is a sport in which participants climb up, across, or down natural rock formations or indoor climbing walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes.
Lion Rock, or less formally Lion Rock Hill, is a mountain in Hong Kong. It is located in Sha Tin District, between Kowloon Tong of Kowloon and Tai Wai of the New Territories, and is 495 metres (1,624 ft) high. The peak consists of granite covered sparsely by shrubs. The Kowloon granite, which includes Lion Rock, is estimated to be around 140 million years old.
Outdoor recreation, such as hiking, camping, canoeing, cycling, or skiing, entails risks, even if participants do not recklessly place themselves in harm's way. In some circumstances, such as being in remote locations or in extreme weather conditions, even a minor accident may create a dangerous situation that requires survival skills. However, with correct precautions, even fairly adventurous outdoor recreation can be enjoyable and safe.
Kaaterskill High Peak is one of the Catskill Mountains, located in the Town of Hunter in Greene County, New York, United States. It was once believed to be the highest peak in the entire range, but its summit, at 3,655 feet (1,114 m) in elevation, places it only 23rd among the Catskill High Peaks. It is, however, the fourth most prominent peak in the range. Due to its situation as the easternmost High Peak, its summit is just outside the watersheds of New York City's reservoirs in the region.
Difficult Run is a 15.9-mile-long (25.6 km) tributary stream of the Potomac River in Northern Virginia in the United States. The area has had many historical uses dating back to the early 1800s. Today, the area is used recreationally by visitors interested in the watershed's variety of options including hiking, biking, fishing, boating, climbing, and bird watching. The wildlife at Difficult Run is vast as 163 different species can be seen depending on the season. There are 41 different soil types found on the trail and alongside the stream. The stream is part of the greater 57.7- square-mile Drainage basin, or watershed, located in the north-central portion of Fairfax County and drains directly to the Potomac River.
Hiking equipment is the equipment taken on outdoor walking trips. Hiking is usually divided into day-hikes and multiple-day hikes, called backpacking, trekking, and walking tours.
Outdoor recreation or outdoor activity refers to recreation done outside, most commonly in natural settings. The activities that encompass outdoor recreation vary depending on the physical environment they are being carried out in. These activities can include fishing, hunting, backpacking, walking and horseback riding — and can be completed individually or collectively. Outdoor recreation is a broad concept that encompasses a varying range of activities and landscapes.
Rupin Pass is a high altitude pass across the Himalaya mountain range in state of Himachal pradesh India. It lies on a traditional shepherd and hiking route which starts from Dhaula in Uttarakhand and ends in Sangla in Himachal Pradesh. The path itself is located across mostly uninhabited areas in the Himalayan ranges at an elevation of 15,250 ft (4,650M) above sea level. Sarasvati Glacier at Sarasvotri at this pass has been identified by some sources as the origin of paleo-river Sarasvati which turned in to icy waters at Netwar, flowing through Paonta Sahib and Adi Badri, Haryana, Punjab, Rajasthan and Gujarat.
The Annapurna Circuit is a trek within the mountain ranges of central Nepal. The total length of the route varies between 160–230 km, depending on where motor transportation is used and where the trek is ended. This trek crosses two different river valleys and encircles the Annapurna Massif. The path reaches its highest point at Thorung La pass, reaching the edge of the Tibetan plateau. Most trekkers hike the route anticlockwise, as this way the daily altitude gain is slower, and crossing the high Thorong La pass is easier and safer.
Sure-footedness is the ability, especially when hiking or mountain climbing, to negotiate difficult or rough terrain safely. Such situations place demands on a person's coordination and reserves of strength as well as requiring sufficient appreciation of the terrain. A person who is sure-footed is thus unlikely to slip or stumble, and will have a good head for heights when required.
The Selvaggio Blu is a trekking route in the territory of the district of Baunei (Sardinia). It was conceived in 1987 by Mario Verin, and Peppino Cicalò (architect), President of the Nuoro section of the Italian Alpine Club. The itinerary extends for over 40 kilometers from the touristic port of Santa Maria Navarrese (Baunei) to the beach of Cala Sisine (Baunei). It takes on average 4 days to complete.
Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. It allows geologists to analyze the distinguishing geological features and structures, plant cover, past history of the site, soil properties, and topography of the study area. It is crucial in the early stage of a geological mapping as it is less time-consuming and offers important data at a minimal price. It is also commonly used in other industries such as forest management, environmental science, disciplines of engineering, and investigating aviation accidents.
A trail difficulty rating system, also known as walking track grading system, walk gradings or trail grades, is a classification system for trails or walking paths based on their relative technical and physical difficulty. A trail difficulty rating system informs visitors about the attributes of walking tracks and helps visitors, particularly those who are not usual bushwalkers, make decisions to walk on trails that suit their skill level, manage their risk, improve their experience and assist in the planning of trails and trail systems.
