Consult lodges for the tipping guidelines. Many lodges have a staff tip box; the workers who receive tips left in the box vary from lodge to lodge. Your guide can advise you, but a general guideline is for each guest to leave $5-$10 per day in total for the lodge staff.
Although tipping is optional and totally up to your personal discretion, it is a safari tradition. Safari guides typically receive between US$ 20-100 per day from the group, depending on the size of the group, the level of satisfaction and length of the trip.
