Yes, there is a minimum age limit to travel on board Kiwi Experience you do have to be over the age of 18.
If you are younger than this and travelling with a guardian, please contact us and we will do our best to get you on board. However, please be aware that most hostel we stay do not allow people stay under the age of 18 with or with out a guardian, so we would not be able to book accommodation if you where allowed to travel with us.
As for maximum age there is absolutely no limit – we’ve had a 72 year old man and a 92 year old woman do Kiwi Experience and they both absolutely loved it!
