In my native German, there is a word for a tree that has grown in a way that it lends itself perfectly for smaller kids to climb around in it – Kletterbaum, which translates, literally, as 'climbing tree'.
Here's an image of what a great Kletterbaum might look like:
Basically any tree with branches that begin low enough for elementary school kids to reach them, and close enough together they can comfortably (and safely) step from one to another.
I've looked around a bit, and online dictionaries suggest the phrase good tree for climbing as the English equivalent. I'm surprised there isn't a more concise term in English for such an essential aspect of childhood.
Or is there?
What do English or American kids and their parents say, when they speak of such a tree?
