The snakes are usually inactive at this time of the year. It is the heat that brings them out. Remember previous safaris at this time of the year and how cold it was in mornings and evenings. At times we barely needed a light jacket. Snakes were a rare sighting for sure. I think only about three mornings we have had where it was just chilly early.
Today it was cold I loved it. This heat will stop and hopefully that is starting to happen now. Do not worry about the snakes we did not see any on the first group. We have all been using our balconies just look on the deck before you step out. Yesterday we watched the elephants from our deck.
