Geocaching is 25 years old, still runs, and has more active users than most AR games shipping in 2026. That fact does not fit the narrative of a category disrupted by newer tech, so it usually gets left out of comparisons written by people whose incentive is to sell you the new thing. We build the new thing and we are still going to leave it in.
Both formats send you to a place. That is the entire common ground. Everything past that, the reward, the maintenance, the community, the trust model, is different, and the differences are what a player of one needs to know before trying the other.
Geocaching, in a paragraph. Somebody hides a physical container at a coordinate, a plastic capsule the size of a pen, sometimes a full-size ammo box, and lists the coordinate on the site. You navigate to within a few metres, find the container, sign the paper log inside, and log the find online. There are around 3.3 million active caches worldwide. The whole system runs on volunteer maintenance, self-policing, and a norm of never leaving trash where you found only a logbook.
AR treasure hunts, in a paragraph. Somebody places a digital object at a coordinate, a token, an NFT, a story beat, a coupon, and the object exists in software only. When you get within the claim radius, your camera renders it into the world and you claim it into your wallet or account. There is no container to maintain. The system runs on GPS plus a stack of other signals verifying you are actually there, and on a chain settling what you collected.
Where geocaching still wins. Battery. Data. A phone-off day in a national park is a geocache day; it is not a Seekprotocol day. If you want to hunt somewhere with no cell signal, the AR games are done and geocaching is not. The physical logbook is also a genuinely good thing that no AR version replicates well, signing your name on paper that has been in the ground for six years and reading the entries above yours is a specific pleasure the software equivalent does not have.
Where geocaching also wins, less obviously. Platform independence. A geocache does not care what phone you have, what account you use, or whether an app company is still in business. The coordinate is on a map; you can navigate to it with any tool. AR treasure hunts, by contrast, live inside a specific app and rely on that app being maintained. When Niantic shut Wizards Unite in 2022 the objects in it stopped existing. When geocaching.com had its worst outage in 2019, the caches were still in the ground, you just could not see the list online for a day.
Where AR treasure hunts win. Dynamic rewards. A cache contains what somebody put in it in 2011, minus what people took, plus what people replaced. An AR drop contains what the publisher placed today, and can escalate, a limited edition that empties as people arrive, a story that unfolds across a route, a reward that scales with visit order. A wooden logbook cannot do any of that.
Portable ownership. The reward for a geocache is a logbook signature and, sometimes, a swag item the finder is expected to swap for something of equal value. Both are lovely and neither has value outside the community. The reward for an AR drop, when the platform is built on a chain, is a token in your wallet you can hold, trade or sell. That is a real difference in the economics of what a publisher will pay to place something.
Verified presence. This is the boring one and it is the important one. Geocaching trusts the finder. A player can log a cache without actually visiting; nothing on the site can tell. In the geocache community this is called armchair-logging and it is frowned on rather than prevented. AR platforms serious about anchored assets verify presence cryptographically, GPS combined with ambient radio, device attestation and motion trace, because they have to. When the reward has actual value, the trust budget shifts and honour system stops working.
The maintenance question, expanded. A geocache is a physical object; physical objects degrade. Rain gets into containers, kids find and take them, forestry workers clear the tree they were tucked into, the coordinate on the map drifts from where the box actually sits. Geocaches need owners to visit and maintain them or they die. An AR drop needs the platform to be alive; it does not need anybody to go and touch a plastic capsule in the woods.
The community difference. Geocaching's community talks on forums that look like they did in 2005 and are wonderful for it. Threads run for years, first-name relationships persist across the country, meetups happen and are usually potluck. AR game communities talk on Discord, at a much faster tempo, more churn per year, more memes, less relationship depth. Which one feels like home depends on what pace of social interaction you actually want.
Overlap in practice. Most geocachers who try an AR treasure hunt do not switch, and most AR players who try geocaching do not either. What happens more often is people do both, and use each for what it is good at, geocaches for the trip out of town, AR for the walk to lunch. A meaningful number of geocachers we have talked to keep Seekprotocol installed as their city-only game. Neither format is losing anyone to the other in a way that shows up in the numbers.
Where a geocacher will feel at home in an AR hunt. The impulse to go somewhere just because there is a thing there. The willingness to walk a kilometre for something small. The completionist streak that fills a map. All of that ports across. Where they will be annoyed: the app-mediated everything, the on-screen distance rather than a good compass, the reward that lives inside a wallet rather than a paper log.
Where an AR player will find geocaching charming. The physical object. The stories in the logbook. The willingness of the community to help a beginner. The permanence, a cache placed in 2004 is often still findable. Where they will find it limiting: no reward beyond the log, no dynamic content, no way to hunt something that was placed today.
A hybrid is possible. A geocache that contains a QR code that unlocks an AR drop nearby is a format we have seen tried at community events and it works surprisingly well, you get the physical satisfaction of finding the container and the dynamic reward of the AR pickup. Nothing prevents publishers from designing more of these, and if the two formats grow up together this is where the interesting overlap lives.
If you have only done one, do the other. If you are a geocacher who has never used Seekprotocol, the closest analogue is a city cache, a coordinate, a short walk, a thing to find, only the thing is rendered rather than plastic. If you are an AR player who has never geocached, pick a traditional cache within a kilometre of your house and try it on a Sunday morning. The formats are less in competition than they look; they are two ways of doing the same underlying thing, and the good version of each is worth the walk.
