|The first geocache takes you to the lakefront and lagoon|
I mentioned this Visit Milwaukee geocache tour in my list of Family Friendly Summer Activities, but still hadn't done it myself. The comments and the publicity it is getting got me totally hooked. I'm a newcomer to geocaching, but it is lots of fun and we just use my iPhone to find caches, though a real gps device might be more accurate. You can do it too.
If you're just getting started, you can create an account at www.geocaching.com. There are some short videos to watch that might make it a bit easier. Then you can select the Milwaukee geocache tour, or any other geocache. If you download the mobile app, you'll find there's a feature where you can find caches near you. We found that there were even geocaches when we went to Japan! This is a worldwide hobby and you may meet people from all over on your adventures.
So the Milwaukee tour has 15 different caches all around the city. This is a good way for you to explore, as well as introduce the city to people who are visiting, or maybe spend a day with a younger person. I do it with my son. These are the neighborhoods where you can find a geocache: Lakefront, Westown, Menomonee Valley, Brady Street, Clarke Square East Side, Third Ward, Walker's Point, Wauwatosa, East Town, Marquette University, Bay View, Water Street, North Point, and River West. You don't have to do them all in a day. Find the one you're most interested in doing (and there are user photos loaded to help you decide) and check it out.
There's another at Havenwoods State Park, and if this is your first attempt, you could start there. They even give you a GPS to use. Good luck on your hunt!
