What are outdoor and adventurous activities?
These are physical activities done in natural, changing places: forests, hills, rivers, the sea, snow. Examples: orienteering, hiking and trekking, climbing, cycling off-road, canoeing and kayaking, sailing, skiing.
They build fitness, but also decision-making, teamwork, confidence and respect for nature. Because the ground, weather and water keep changing, you must read the environment and adjust.
Technology helps: GPS watches, phone map apps, weather forecasts, heart-rate monitors. But batteries die and signals drop, so a paper map and compass are still the main skill.
Orienteering: map, contours and compass
Orienteering is a race where you visit control points (orange-and-white flags) in order, using only a map and compass.
- Set (orient) the map: turn it so North on the map points to real North. Then left on the map is left on the ground.
- Contour lines join points of the same height. Close together = steep; far apart = gentle.
- Scale: 1:10 000 means 1 cm on the map = 100 m on the ground.
- Bearing: the angle from North, clockwise, 0° to 360°. To walk on a bearing: point the compass base plate arrow at your target, turn the dial until its N lines up with the needle's North, then keep the needle in place and walk.
Pacing: count double steps over 100 m on flat ground (often about 60–70) to measure distance.
Route choice and decisions
Between two controls there are often several routes. Compare:
- Distance: shorter is not always faster.
- Climb: a common rule is that 10 m of climbing costs about as much time as 100 m of flat walking.
- Ease of navigation: following a path or stream (a handrail) is safer than cutting through forest.
- Attack point: go fast to an easy-to-find feature near the control, then go carefully.
If you are lost: stop, stay calm, find where you last knew you were, and set the map again.
Climbing safely
Indoor and outdoor climbing use a harness, helmet, rope and a belay device.
- Top-rope climbing: the rope goes from the climber up through an anchor at the top and down to the belayer, who takes in slack and locks the rope if the climber falls.
- The climber ties in with a figure-of-eight knot. Partners check each other's knot, harness buckles and belay device before every climb (a buddy check).
- 3 points of contact: move one hand or foot at a time.
- Push with the legs (strong) more than pulling with the arms; keep hips close to the wall.
- Clear calls: "On belay?" "Belay on." "Climbing." "Climb on."
Bouldering is climbing low problems without a rope, over crash mats, with a spotter.
Planning, safety and leave no trace
Before: check the weather and daylight; plan the route; tell someone your route and return time; check fitness and equipment; never go alone.
Kit: map, compass, water, food, warm and waterproof layers, first-aid kit, whistle, torch, charged phone. For water sports: a buoyancy aid (life jacket), and only with a trained supervisor.
Risk assessment: list hazards (slippery rocks, cold, lightning, deep water), how likely and how serious they are, and what reduces them.
Emergency: 6 whistle blasts or torch flashes in a minute = help needed. Stay together, keep warm, call the local emergency number (112 works in India and the EU).
Leave no trace: stay on paths, camp on hard ground, carry all litter home, do not pick plants or feed animals, keep noise low.
Try it: a schoolyard compass course
With an adult, place 5 markers around your school ground. From a start point, write down the bearing and pace count to each marker. Swap sheets with a friend: can they find your markers using only your bearings and paces? Then try the free-play step in the 3D: guess the bearing first, then check how far off you are.
Key formulas and definitions
- Bearing = angle from North, measured clockwise (N 000°, E 090°, S 180°, W 270°)
- Map scale 1 : 10 000 → 1 cm on map = 100 m on ground
- Rule of thumb: 10 m of climb ≈ 100 m of flat walking in time
- Back bearing = bearing ± 180°
- Distance off course ≈ distance walked × sin(error angle)
- Distress signal: 6 blasts / flashes per minute
Worked examples
1. On a 1:15 000 map two controls are 4 cm apart. How far is that on the ground?
1 cm = 15 000 cm = 150 m. So 4 cm = 600 m.
2. Your bearing to a hut is 060°. What bearing takes you back to the start?
Back bearing = 060° + 180° = 240°.
3. Route A is 800 m with 60 m of climb. Route B is 1200 m on flat ground. Which is likely faster?
Route A: 60 m climb ≈ 600 m flat, total ≈ 1400 m equivalent. Route B ≈ 1200 m. So B is likely faster, and easier to follow.
4. You walk 1 km with a 5° bearing error. About how far off are you?
1000 × sin 5° ≈ 1000 × 0.087 ≈ 87 m. Small errors grow with distance, so aim for a large feature near the control.
5. Your pace count is 65 double steps per 100 m. How many for 350 m?
350 ÷ 100 = 3.5; 3.5 × 65 ≈ 228 double steps.
Common mistakes
- Reading the compass with the map not set to North, so left and right get swapped.
- Choosing the shortest line on the map without looking at contours and climb.
- Starting to climb without a partner check of knot, harness and belay device.
- Going out without telling anyone the route and return time, or trusting only a phone.
