I have a "basic" membership with Geocaching.com. I have not received any spam from them; including pushes to upgrade to a premium account. Doesn't appear that have sold my contact info. Would recommend this site to anyone interested in Geocaching.
Die beste und umfangreichste Seite rund um Geocachen. Absolut Kinderfreundlich, absolut zu empfehlen. Keine obszöne Werbung, keine nervigen Popups, ein ausschließlich seriöser Anbieter. Sogar diese sind noch im Internet zu finden...
I think for starters this is the easiest way to start and also the most helpful. My family and I are enjoying a new hobbie and of all the sites and apps I have tried this is the one I use the most. TFTC
This is a great and fun way to spend time on your own, with friends, family, and just to have fun outdoors. Check out geocaching.com for more information about how to start enjoying this wonderful way to play the world's greatest treasure hunt game that is child friendly.
I don't normally rate site's as child safe as I don't have children in my home, but I do have relatives that are of the age that I've taken geocaching with me, so I scored this site with a high rating for child safety. They use the site to report their found geocaches, and I communicate with them and monitor their progress in their hunts for geocahces on the site.
This is a great way to have fun that doesn't cost any money (you can spend money if you get into the hobby and so desire, but you can do it for free). Best of luck on the hunt!
