Yes I do. I've found over 350 and hidden over 30. I haven't done any in the past couple of months and I'm not as active with it as I used to be but once the winter ends and the snow all melts I'll be out on the trails and serching for more. It's a neat hobby!

I don't have GPS or whatever it is to do it. My DD lives in Holland MI. I went to the sight and it said they have a lots of the caches around there so I told her about it. The haven't started it though.

We sometimes Geocache with our neighbors who are pretty active finding and leaving caches. We must have walked five miles in the desert one time looking for a cache. Great exercise. You're so busy exploring everything around you that you forget that you're putting in some serious walk time (assuming you don't find the cache right away). The neighbors do it because it takes them places they would normally never see or even have a reason to visit.

Jodi-

Can someone explain more about how you do this? Is there an app for that :) ?
What type of items do you find in the cache? Do you leave it there for someone else to find? What type of items do you place in a cache if you are the one who hides it?
I like to walk and enjoy being outdoors, it sounds like a perfect hobby for me!

no I don't since I can not walk well and most of the places are not wheelchair accessible but I have several friends who do. One friend and her boyfriend take weekend trips away and do geocaching.

shay13 it varies some contain a log book for you to record your info in, some have trinkets, you can leave trinkets or what ever you want, the cache is usually pretty small. You use a GPS to find the long and lat where the cache is but you have to find it and they are hidden. Just google it there are groups you can join it is a good way to meet other people and to get outdoors and exercise.
There may well be an app for that LOL I have not looked.But most smart phones now do have GPS and maps.

For those that want a milder version try doing book crossing where you set a book you have read loose in the wild, you tag it, turn it loose at some location, then keep track of it on the bookcrossing website. It is fun too and I have done that, usually leave mine in medical offices or hospitals. Or you can go out and find a book, post your find, read the book then turn it loose again.

You don't need a GPS if you have a smart phone with a built in GPS. I have an iPhone and there is a geocaching app you can download and use. I usually use my GPS because I find it more accurate but I have used my iPhone. The iPhone is better in some ways because you can read the hint and previous logs which could also help you find it easier.

Yes, we are geocachers. It has been especially rewarding on vacations, as the caches will often take you to local gems, such as a special view or little known sight that the average tourist might miss. The hides are rated for difficulty and for terrain - so it can be as easy as walking down the street (including being handicapped accessible) to being a very challenging hike. The hides can be big as day easy, or diabolically difficult - like the one in a hollowed out pinecone we found.
I've put the link to Geocaching.com below, if you want to learn about it

We bought a motorhome and plan to be out and about in it and I found out that many many people who travel in RV's do this as a hobby...and I thought it would be fun. I think you could find lots of them without a GPS but that is the idea...

Shay it is like a treasure hunt....the treasures are just trinkets and a log book to sign. It's not really about the treasures but about the thrill of the hunt. There are lots of other things involved like traveling coins and "first to find" rewards (usually one nice prize for the first person who finds it...

No, but signed up for it last year. Was going to do one near here but the weather was bad and then I got busy with other things. I may have to look a few up on their site and try it when the weather is nice.

Sorry to bring this up again but I thought anyone interested my enjoy this map. Just put your own address in the slot on the left and it will show you the cache's hidden in your area.

Thanks everyone for providing more information! It sounds very interesting and a great way to be active. I love the idea of the log book in the cache, sort of like who has stayed at rental vacation home. So I now have another question, if a cache has a trinket and you take it; does the person who starts the cache replenish for other "finders"? Or if I'm the finder, should I leave a trinket for someone else to find in the hidden cache? I'm just trying to understand the etiquette of geocaching (sp?).

Sometimes the person who hid the cache will go back (once a year maybe) to check on the cache, replace the log book, make sure it isn't wet or damaged and replace the swag (trinkets).

If I take something from a geocache I always put something back in. Coins are popular (especially foreign coins) as well as lapel pins and little toys.

din't join but did put im my zip code and the location (on one) mentioned is just a couple of blocks from me, lol! what fun...

I signed up but never did it. I see there are a few near my home, mostly along hiking paths. Can you find them with the kind of GPS you use n your car? I don't have (or want) a smart phone.
