They could organize a tour for our family, just a little bit more expensive, but worth with a three-years old. We spent an amazing day along the Sandwich cost. The landscape is among the most beautiful we have ever seen. We saw a jackal, spingbooks, lizards and other small animals. The picnic's food was good and fresh. Our guide, Burger, was friendly, helpful and has patiently answered all our thousands of questions. At the end, he even offered to drop out us in Swakopmund center as we wished and to bring our car seat and our jackets to our hotel.
Unfortunately we needed to shortcut the tour as our daughter started beeing sick. We will try again when she is older.
