Is there a basic fitness level required at entry level?

For BASE jumping you’ll need a good all-round fitness level. A healthy cardio vascular system helps the hike back up to the top just that little bit easier! BASE jumping is not something that you can just walk into, without the right training and experience you won’t walk away from your first BASE jump. Before you even think about doing a BASE jump you will need to become an experienced and capable skydiver, well versed in the arts of freefall and parachute flight. There are no shorts cuts in this game!
