#1 Blaze

A marking, often a painted or affixed patch, on trees or rocks along a trail that indicates the path of the trail. Blazes are essential for navigation, helping hikers follow the trail’s route without getting lost.

#2 Bushwhack

Off-trail navigation through dense forest or underbrush, where no clear path exists. Bushwhacking requires a strong sense of direction and is more demanding, as hikers make their way through untouched wilderness.

#3 Cairn

A human-made pile of stones often found on trails. Cairns serve as navigational aids in landscapes where the trail isn’t obvious, guiding hikers in the right direction, especially in alpine or barren terrain.

#4 Descent

The act of moving downward from a higher point, such as coming down a mountain or hill. Descent can be challenging and requires careful footing, especially on steep or rugged trails.

#5 Elevation

The height above sea level at which a particular point on the landscape sits, typically used in the context of reaching the top of a mountain peak or plateau. Higher elevations can mean thinner air and more challenging hiking conditions.

#6 Gaiters

Protective garments worn over the lower part of the pants and shoes. Gaiters prevent debris, snow, and water from entering a hiker’s footwear, offering an extra layer of protection against the elements.

#7 Hydration pack

A type of backpack designed specifically for easy drinking while on the move, featuring a built-in reservoir or bladder that holds water. A tube connected to the bladder allows the hiker to drink hands-free without removing the pack, promoting better hydration during long treks.

#8 Incline

Refers to the upward slope or gradient of a trail in hiking. The incline can vary from gentle slopes to steep ascents, affecting the difficulty level and physical exertion required from hikers. Managing inclines often requires good pacing and stamina.

#9 Trailhead

The starting point of a hiking trail, often marked with signs or information boards. Trailheads serve as gateways to the wilderness, where adventurers begin and end their outdoor journeys.

#10 Loop

A type of hiking trail that forms a circle, allowing hikers to return to their starting point without retracing their steps. Loop hikes provide a variety of scenery and are popular for their convenience.

#11 Marker

Markers are visual cues, such as painted blazes, symbols, or signs along a trail, designed to help hikers follow the intended path. They are crucial for navigation, especially in remote or less-traveled areas.

#12 Out-and-back

An out-and-back hike refers to a trail that leads to a destination, then requires hikers to return the same way they came. It’s ideal for seeing a specific landmark without completing a loop.

#13 Peak

The summit or highest point of a mountain or hill. Reaching a peak is often the goal of a hike, offering panoramic views and a sense of accomplishment to those who make it to the top.

#14 Ridge

A long, narrow elevation of land, often with steep slopes, that connects peaks. Hikers may walk along ridges to experience dramatic landscapes and potentially challenging terrain.

#15 Scramble

A scrambling section of a hike involves using both hands and feet to climb over rocks and rough terrain, often without technical climbing equipment. It’s a step up from regular hiking, requiring

#16 Switchback

In hiking, a switchback is a zigzagging path that makes steep terrain more manageable by reducing the incline of each segment. This technique allows hikers to ascend or descend hills and mountains more easily, preventing overly steep climbs and minimizing trail erosion by distributing wear evenly across a broader area.

#17 Thru-hike

An end-to-end long-distance trail hike — often taking several months — completed in a single trip, such as the Appalachian or Pacific Crest Trail. This demanding adventure tests endurance and commitment to trekking.

#18 Topo

Short for topographical map, a detailed and accurate graphic representation of natural and man-made features on the ground. Hikers use ‘topos’ to navigate terrain, showing elevation changes with contour lines.

#19 Traverse

To travel across or through a specific area or terrain, usually horizontally rather than ascending or descending. Traverse often refers to a challenging section that requires careful navigation and balance.

#20 Ultralight

A minimalist backpacking philosophy that emphasizes carrying the lightest and simplest gear safely possible. Ultralight hikers meticulously choose gear weighing mere ounces to reduce their packs’ overall weight.

#21 Vista

A wide-ranging view from a high point along a trail, often sought after by hikers for the panoramic scenery and photo opportunities it provides. Vistas are the breath-taking rewards for a hike’s exertion.

#22 Waypoint

A reference point in physical space used for purposes of navigation, often marking a significant point on a GPS track, such as a turn, a start or end point, or a place of interest.

#23 YDS (Yosemite Decimal System)

The Yosemite Decimal System (YDS) is a scale used to rate the difficulty of hikes and climbs, primarily in the United States. It ranges from 1.0 (easy walk) to 5.15 (extremely difficult technical rock climb).

#24 Zero Day

A day spent without hiking, typically used as a rest day for long-distance hikers or thru-hikers to recover from the rigors of the trail. Zero days help prevent injury and mental burnout while on extended treks.

#25 Alpine

Referring to high mountain environments above the treeline, alpine areas are characterized by harsh conditions, minimal vegetation, and often snow-covered terrain. These regions require careful navigation and specialized gear.

#26 Base Layer

The clothing layer worn directly on the skin, designed to manage moisture and regulate body temperature during hikes. Base layers are often made of moisture-wicking materials like merino wool or synthetic fabrics for optimal comfort.

#27 Compass

An essential navigation tool that uses the Earth’s magnetic field to point toward magnetic north, aiding hikers in wilderness travel. Modern compasses are often paired with maps to assist in route finding and orientation.

#28 Day Hike

A hike that is intended to be completed in a single day, ranging from a few hours to a full day’s walking. Day hikes don’t require overnight gear and often suit casual hikers or those with limited time.

#29 Footpath

A trail or path that is specifically designed for people to walk on, which can range from well-maintained boardwalks to narrow, natural trails. Footpaths allow hikers to traverse through natural environments with minimal impact.

#30 Gore-Tex

A waterproof, breathable fabric membrane that is commonly used in outdoor and hiking gear, including jackets, boots, and gloves. Gore-Tex keeps moisture out while allowing sweat vapor to escape, making it ideal for keeping hikers dry and comfortable in various weather conditions.
