Yes you can go, but you need to arrange a transfer across to the Zambian Side (Royal Livingtsone Hotel). This can be done through your travel agent, Hotel or we can arrange it for you. The cost is currently $14 per person one way and it takes about half an hour including border post formalities.
If you require a visa to enter Zambia these will have to be purchased at the border and if you required a visa to enter Zimbabwe then you will have to buy another visa on you way back into Zimbabwe unless you bought a double netry visa when you first arrived.
