There are no weight restrictions. When you book, if someone in your group is over 100kg if you could please let us know as this helps us when we are allocating you a place to stand in the balloon. 

The safety requirement is that all passengers can climb in and out of the basket unassisted. The basket stands 1.2 meters in height and there are two foot holds in the side of the basket that you can use like a ladder to assist the climb and stand for the duration of the flight.
