Inverdoorn offered an generally enjoyable experience the animals, facilities and hospitality at the reserve are great. If this is your first trip to Africa and Cape Town is your only destination then this is a good option for an encounter with the famous animals, as well as a great photo opportunity! Be sure to select your seat in the safari vehicle wisely, legroom is at a premium!
When selecting this tour it is important to consider the transfer by the tour operator. From pick-up it took over four hours to get to the park. This in itself is ok, however in my opinion the guide was over-preoccupied with the threat of bad traffic and timings of the day. It became very apparent that the advertised option of enjoying the pool facilities at the resort wasn't an option due to the driver wanting to get back on the road as soon after lunch as possible - despite then stopping at a winery and shop on the way back.
If you have a good amount of time in Cape Town and you really want to see some of the animals then this is probably worth a day of your trip.
