We booked a safari with Explorer Kenya this year and in 2011.
Last year we went to Masai Mara and Lake Nakuru. Since we were very happy with the organisation and our personal driver John, we decided to book another safari tour with the same company and driver and we were very satisfied again. This year we went to Samburu, Lake Naivasha and Masai Mara.
Booking the trip was very easy and friendly. And when asking questions by e-mail, the answers came within 24 hours or less. Which is really nice.
Our driver and guide John is very friendly, funny, relaxed and discrete driver who tried to show us a maximum of game possible. We always felt extremely safe with his driving skills.
I would ask for his services a third time! So I really recommend him as a driver and guide.
Last year, we stayed in the Serena lodges. The Serena lodge in Masai Mara and tents were incredibly nice and food was delicious. On the other hand, Serena in Lake Nakaru was a bit less accomodation wise.
This year, we stayed in Sopa Lodge: really enjoyed the Sopa lodges in Samburu and Lake Naivasha but the rooms in Sopa lodge in Masai Mara were a little bit less luxurious and very dark, even though the staff was extremely friendly, as always.
So if you are looking for reliable organization: certainely check the explorer kenya website.
