Bouldering: climbing on large boulders, either for practice or as a sport in its own right. (Oxford American Dictionaries)
Finding a decent boulder to climb on is harder than it may seem. Here are some steps to follow in finding a place to climb for practice or sport.
This instructable is written so that a person doesn't need to be able to identify different types of rocks or rock formations (another instructable waiting to happen). I apologize to those climbers that feel that most of the information conveyed here is common sense. However, I would appreciate feedback if you feel that I left something out.
I hope to update this regularly with pictures, comments and advice as I find more places to climb.
(And remember, climbing is inherently dangerous. You do so at your own risk.)
Step 1: Drive/walk/bike and have a look around.
Generally speaking, in order to climb, one needs to have vertical elevation. So, you are going to want to get off your couch and travel around your town looking for boulders (obviously), hills (may potentially have an exposed rock face) and public parks (you never know when city planners will drop in a boulder for decoration).
Of course, if you live somewhere as flat as a pancake, you are mostly out of luck. For argument's sake, I will include on my list of places to boulder retaining walls and canals made of natural rock (or stone bricks). However, technically speaking, climbing man-made structures is considered "buildering" and usually quite illegal and dangerous.
