Anyway to know all details of trees grown using RandomForestClassifier in scikit-learn?
I think Terence Parr's answer is now partly outdated. You can get the same (and more) with:

print("Tree depths: ", [t.get_depth() for t in model.estimators_])
print("Tree number of leaves: ", [t.get_n_leaves() for t in model.estimators_])
