Remember to dress a little more conservatively, don't wear shorts or sleeveless tops. You may need to take off your shoes or remove all leather items (don't worry, the shoe minder will take good care of them). Check with your guide if photography is allowed or not. If guide is unavailable then consult your cab driver or any care-taker or nearby Government official. Bear in mind that some sites might not admit women or might be reserved for followers of that faith.
