Yes. However there will be costs if you cancel. These will depend on how long before the trip start date you cancel. The details of the cancellation costs will be clearly described in your Trip Contract.
Generally the terms for our African safaris are more stringent than our European trips. This is because many of the small lodges / camps and the guides are unlikely to refill the time allotted to your booking easily. Due to demand they often have to decline trips as soon as your booking is confirmed, so a later cancellation results in missed opportunities and business. They usually also have limited short seasons. If you think there is a possibility you may have to cancel your trip, it is advisable to contract a “Cancel for any reason” insurance within 2 weeks of paying the deposit for a trip, and to carefully read the conditions beforehand.
