I refused the aircraft for an inoperative APU based on enroute terrain considerations as well as forecasted weather conditions in ZZZ1 at the expected time of arrival. The safest course of action was to have an aircraft with an operative APU. At a minimum having either (preferably both) a backup pneumatic and/or electric component provided by the APU is always the safest course of action in any sense.
