There are so many suggestions I could make but would need more specificity - what camera equipment, where to go, what clothing, etc. Where are you going in Botswana? Will you be by yourselves or with a group?
Botswana is a wonderful and varied place. I've always gone with a good photo group. No more than 3 per vehicle so that we had plenty of room for our cameras and could photograph right and left. Most importantly, we had drivers who knew that we had to leave early each morning before the sun was up, so that we would be there for the best morning light and the animals are most active early - photography is more important that a long, leisurely breakfast. We would be back to eat by maybe 11am when the good light was gone.
If you wanted to do Hide photography, then there is a place in Botswana called Mashatu.
Wonderful series.
I have a family trip planned for Botswana in August 2023. I went to South Africa a few years ago, but it will be my first time in Botswana.
I don't know if I will pass for that location; I hope so; I need to ask my wife. Have you any suggestions for the trip?
Backing up what Ivan has said, Botswana is a fantastic place. I have spent a good deal of time in the Okavango and at Mashatu. Mashatu is on the border with South Africa and accessed through Pont Drift border post. Mashatu has been sold recently, I was friendly with the previous owner. I believe it is the biggest privately owner reserve in Southern Africa. The hides there are fantastic, particularly the sunken "Matabole" hide. I know that up until recently the hides were being run by C4 Images, who also have specialist photography vehicles. It is a bit isolated from the rest of Botswana and reality is more a part of South Africa. If the budget allows, I would strongly recommend looking at Wilderness Safaris. They have a range of amazing lodges in ZA, Botswana, Zambia, Namibia & Zim. They also run the aircraft linking many of the camps. I have been using them for over 20 years.
