The park is open daily from 16th October to 30 June, although management reserves the option to close earlier if the rains begin before the end of June. The opening hours are scheduled to accord roughly with the seasonal variations in climate, as well as with the length of the day at different seasons. There is always a mid-day break, so that employees may eat lunch and rest and the animals may have a respite, too. Morning Safari is about 6 hours, and the evening safari is about 3 hours.

These hours are subject to change because of special conditions: for example, heavy rain showers may make park roads temporarily hazardous, or official activities such as census taking may be scheduled. In practice, "sunrise" and "sunset" are interpreted as "dawn" and "dusk," with vehicles being admitted at 6:30 A.M., for example, if sunrise occurs at 6:50. The gate attendants tend to be stricter about exit times, since darkness follows sunset quite rapidly at this latitude.
