Optionals are activities that one may enjoy that are not included in the trip price. These can be taste/ability specific and not everyone will want to participate. TIA Safaris will provide you a list of optionals available for each safari. The Gorillas, rafting on the Nile or Zambezi, Chobe Overnight, Swakopmund activities, ballooning in the Maasai Mara, Zanzibar activities, and Vic Falls are paid in US dollar.
