If your tour ends in Zambia you can certainly try to book an excursion to the Thorntree (sp) Elephant Sanctuary. We learned so much there. We booked our excursion through the Livingstone Hotel. We had great interactions with the Elephants. It was wonderful watching the babies interact with the adult elephants. I think there is also a trail ride (if you can call it that) thru the river. I didn't participate in this activity. I fed the baby elephants. Their ears are like velvet to the touch. I sat on an adult elephant and was wrapped in his trunk..it was a really cool experience.
I know this was back in 2010, but do you remember how long the experience was, door to door? I assume transportation to and from the Royal Livingstone was provided? Who was the provider? According to the current info the Royal Livingstone sent us, their on-site(?) booking agent, Bushtracks, can arrange elephant experiences (both elephant backed safaris or elephant interactions only), with Safari Par Excellence, starting up river at the Thorntree Lodge at Mosi-oa-Tunya National Park (19 km/23 min.) or with Mukuni Big 5 which is closer (3.5 km) but their experience shorter.
Anyone else with first hand info please join in. Thanks.
