Navigation & Orienteering

GPS has made backcountry navigation easier, but it has not made it foolproof. Batteries die, screens crack, signals drop in canyons, and apps crash at the worst possible moment. Knowing how to read a topographic map, take a bearing with a compass, and navigate by terrain features is a foundational backcountry skill — not a relic of a pre-digital era.

Even if your GPS is working perfectly, understanding how to read the landscape around you makes you a better route-finder, helps you recognize hazards earlier, and gives you the confidence to travel in conditions where visibility is poor or trails are buried under snow.

Core Skills

• Topographic map reading — Understanding contour lines, scale, declination, and how to translate what is on the map to what you see in front of you. This is the single most important navigation skill.
• Compass use — Taking and following a bearing, triangulating your position from visible landmarks, and adjusting for magnetic declination. A baseplate compass is lightweight, indestructible, and has no battery to fail.
• GPS and digital tools — Using handheld GPS units and smartphone apps effectively, including downloading maps for offline use, setting waypoints, and understanding datum and coordinate systems.
• Terrain association — Matching the features around you to the map without needing a compass or GPS. Ridgelines, drainages, saddles, and cliff bands all tell you where you are if you know how to read them.
• Route finding — Choosing a travel line through complex terrain based on efficiency, safety, and your group's abilities. This is where map skills, weather awareness, and terrain judgment come together.

Free Resources

• USGS Topographic Maps — Free downloadable topographic maps covering the entire United States. The topoView tool lets you find and download historical and current USGS quad maps in PDF and GeoTIFF formats.
• CalTopo — A free online mapping tool that lets you create custom topographic maps, plan routes, calculate slope angles, and print maps for the field. The free tier covers most recreational navigation needs.
• REI Expert Advice (YouTube) — REI publishes clear, well-produced tutorials on map and compass basics, GPS navigation, and trip planning. Their "How to Use a Compass" and "How to Read a Topo Map" videos are solid starting points.
• Orienteering USA — The national governing body for orienteering in the US. Local clubs run events where you navigate a course using a map and compass — a fun, low-stakes way to practice your skills in a social setting. Many events are free or have a small entry fee.

Paid Courses

Hands-on instruction accelerates the learning curve significantly. A weekend course with an experienced instructor will teach you more than months of self-study, because navigation mistakes are hard to recognize on your own until they compound.

• REI Outdoor School — Offers map and compass classes, GPS navigation workshops, and backcountry navigation courses at locations across the country. Many classes are low-cost or free for members, and they cover the fundamentals well.
• The Mountaineers — Their navigation courses are some of the most thorough available to recreational users. Includes classroom instruction and field outings. Based in the Pacific Northwest, with courses structured around their climbing and scrambling programs.
• NOLS — Navigation is woven into most NOLS backcountry courses rather than offered as a standalone class. If you are considering a NOLS expedition, you will come out with strong map and compass skills as part of the broader curriculum.
• Local hiking and mountaineering clubs — Many clubs affiliated with the American Hiking Society or regional mountaineering organizations offer navigation workshops and mentored outings. These are often the most affordable option and connect you with experienced navigators in your area.
• Orienteering clubs — Competitive orienteering is a fast-track for building navigation skills. Many local clubs offer beginner clinics before events, and regular participation will sharpen your map reading faster than almost anything else.
