Geocaching

Somebody hides a waterproof container with a logbook in it and publishes the coordinates. You navigate to within a few metres using GPS, search, find it, sign the log, put it back exactly as you found it, and record the find online. That is the entire game.

What makes it more than that is scale and variety. There are caches on every continent, in city centres and on remote hillsides. Some are film canisters magnetically stuck to the back of a road sign; some are ammunition boxes half a day’s walk from a road; some require solving a puzzle before you get real coordinates at all. The hiding is as much of a craft as the finding.

The characteristic experience is being sent somewhere specific and pointless-seeming, and discovering it is not pointless: a Victorian boundary marker, a view you did not know existed, a bridge with a plaque on it. Geocachers describe this as the real reward and they are broadly right.

The first stretch of geocaching is about learning to see: what a container looks like when it does not want to be seen, how far the coordinates can be out under tree cover, and where people hide things. That happens on its own after a few dozen finds and it is why the early hobby is quietly addictive.

What comes next is a choice about what you want out of it, and the branches are genuinely different pastimes sharing an app.

• From traditionals to multis and mysteries — The natural first widening. A multi-cache makes you work a route rather than a point, and a mystery has a puzzle between you and the coordinates. Mysteries in particular are a different hobby — some are solved at a desk over an evening — and they are where a great many long-term geocachers end up.
• Harder terrain, and the equipment that goes with it — The terrain rating is doing real work at the top of its range: caches that need a boat, a rope, or a long walk in. Each of those is a skill and a kit list borrowed from another hobby, and none should be attempted because a cache is there rather than because you can already do it safely.
• Hiding your own, which is the real step up — It changes what you notice on every walk. A good hide is about the place being worth visiting rather than the container being hard to find, and maintaining one is an ongoing commitment that a surprising number of people underestimate. Reading the hiding guidelines properly before placing anything saves a listing being rejected and, more importantly, saves a landowner being annoyed.
• Trackables and their etiquette — Items with their own identity that move from cache to cache with a goal set by their owner. They are the most social part of the hobby and the part most often done badly — picking one up and keeping it for months is the commonest complaint in the community.
• Events, and the fact that this is a social hobby underneath — Organised meet-ups are a cache type of their own. They are where local knowledge, permissions and puzzle help all circulate, and most people who stay in the hobby for years arrived at that through an event rather than through the app.
• Streaks, challenges and grids — Self-imposed structures — a find every day, a full grid of difficulty and terrain combinations, a county completed. They are a real motivator and they are also how the hobby stops being fun for some people, because the streak starts making the decisions. Worth knowing which one you are.
• Cache maintenance and giving back — Every cache someone finds is one somebody else keeps working. Adopting an abandoned cache, replacing a wet log for an owner, and logging a needs-maintenance honestly rather than a smiley are what keeps a local area worth visiting, and they are the least visible and most valued part of the hobby.

1. 1

   Step 1: Install the app and make a free account

   The main platform is geocaching.com. The free tier is enough for your first several months. There are smaller alternative platforms with their own caches, but start on the big one because that is where the density is.

   You will know it worked when: You can see caches on a map around you, which will be more than you expect.

2. 2

   Step 2: Filter to Difficulty 1–2 and Terrain 1–2, size Regular or Large

   This is the single most useful piece of advice for a first outing. Every cache carries two five-point ratings and a size class. A "micro" at Difficulty 4 in an urban centre is a genuinely hard find and is the reason many people give up on their first attempt.

   You will know it worked when: Your first find takes ten minutes rather than forty and does not end in defeat.

3. 3

   Step 3: Read the listing before you go, including the hint and recent logs

   The hint is usually rot13-encoded so you can choose not to read it. Recent logs tell you whether the cache is still there — several "did not find" entries in a row usually means it is gone, not that you are bad at this.

   You will know it worked when: You are searching for something that exists.

4. 4

   Step 4: Take a pen

   This is the beginners’ mistake everyone makes exactly once. Small caches contain a rolled log strip and nothing to write with. A find you cannot sign does not count.

   You will know it worked when: You can actually log the find.

5. 5

   Step 5: Search from the GPS, not with it

   Phone GPS is typically accurate to around 3–5 metres in the open and much worse under trees or between buildings. Walk to zero, then put the phone away and think like the person who hid it: what is the most obvious hiding place within a five metre circle?

   You will know it worked when: You find it. The transition from staring at an arrow to reading the landscape is the core skill.

Practical points that come up repeatedly:

• Tell someone where you are going — Especially for rural caches, where a twisted ankle a mile from a road is a genuine problem.
• Phone battery — GPS and screen-on time drain a phone quickly, and your map, your torch and your means of calling for help are the same device. Carry a power bank for anything beyond an hour.
• Ticks — Rough grassland and woodland edge in Britain carry ticks, some of which transmit Lyme disease. Cover legs, check afterwards, and remove any tick promptly with a proper tick tool.
• Do not put your hand in blind — Look first. Wasps, nettles, brambles and sharp metal all live in the same gaps caches do.

• Replace it exactly as you found it — Same place, same orientation, same camouflage. A cache replaced badly is a cache the next person cannot find, and the commonest cause of a container going missing is a well-meaning finder putting it somewhere "better".
• Trade evenly or not at all — If you take an item from a cache, leave one of equal or greater value. Nothing edible, nothing scented — animals will chew through a container to get to it — and nothing that could be dangerous to a child.
• Watch for muggles — The term for non-geocachers, borrowed and universally used. Retrieving a cache in front of an audience risks it being removed by someone who thinks it is litter, or reported as suspicious. Wait, or come back.
• Log honestly — Including "did not find". DNF logs are the signal that tells an owner to check their cache, and suppressing them out of embarrassment breaks the maintenance system that keeps the game alive.
• Cache In Trash Out — A long-standing convention of picking up litter while you are there. It is why landowners tolerate the activity as widely as they do.
• Do not publish spoilers — Photographs of the hiding place in your log ruin the find for everybody after you.

Trackable items are the other half of the culture. A Travel Bug or geocoin carries a code and a goal set by its owner — "travel to Japan", "visit every county in Wales" — and finders move it from cache to cache, logging each move. Some have travelled tens of thousands of miles across many years. Picking one up carries an obligation to move it on reasonably promptly rather than keeping it.
