The Kasane, Chobe River border is the nearest access to Namibia. Simply cross the river, get out of your boat and you are crossing the border. Possibly one of the most relaxed border points I have ever seen. Walk up the hill and left at the baobab tree and a tiny office houses the border official ready to stamp you into Namibia. From here, people either stay on Impalila island or spend a few days on one of the houseboats that cruise up the Chobe river, passing the large riverside lodges and entering into territory less accessible to tourists.
