Weather permitting we also train outdoors. It is quite a different experience from training in the Dojo. You're no longer confined to the Dojo . You will find it challenging training on different terrain. You have nice soft Tatami mats to land on in the Dojo, so your ukemi (rolling & breakfalls) will be put to the test in its natural environment.
Training out in the forest late at night is an experience not to be missed. Not only is it a challenge for any practitioners skills as the sun sets, but for all your senses as the forest grows quiet and tranquil.
