Our trip to Namibia was a truly diverse experience. It is a country that is not yet over-exposed to tourism. The safari element of the trip pretty much guarantees a huge diversity of wildlife (we went during a season where there is not a huge amount of wildlife around and still saw plenty!), both animals and birds.
Outside of the safari both the desert elements and the stay in Swakopmund amazed us - both very different.
Finally, whilst it took a few days to get used to camping we're glad we did the trip this way, as it really brought the group and the support staff closer together than we've experienced on other trips.
